Atovigba Department of Curriculum and Teaching, Benue State University, P.M.B. 102119 Makurdi Nigeria Abstract: The study attempts to prove the Riemann hypothesis by showing that the Riemann zeta function converges to zero and absolutely converges to 0. The work uses the mean and mean deviation approach of solving quadratic equations, in identifying the roots of an auxiliary energy equation of some second order homogeneous ordinary differential equation. The energy equation is brought about by simultaneously treating energy generation by electrons and quarks. A set of complex roots of the auxiliary equation takes the form of the set of analytic zeros s = ½ + it of the Riemann zeta function H(s). s varies partly as ½ and partly as some t, t being a function of the mass (m) of particles and k distance (or frequency) achieved by the particle. The Riemann zeta function is treated as an infinite series which converges to 0 as t tends to infinity and which converges absolutely to 0 as t tends to infinity. Key words: Absolute convergence, convergence, critical line, distance, electrons, energy, mass, mean and mean deviation approach, quarks, Riemann zeta function, speed, zero whose term is a fraction and attempts to treat the series to varying values of s, noting particularly that s depends on t, hence it is actually t that varies as first entries to produce values of the Riemann zeta function for any n positive integer. The work studies the behavior of H(s) for any n = 1, 2, 3, … as t varies, the aim being to locate if the series tends to zero for the general term n provided t tends to infinity. Selberg, in an interview with a web group, Not Even Wrong (2008), about attempts by him and other notable mathematicians to solve the Riemann hypothesis, emphasizes the importance of simplicity in mathematics and notes that the simple ideas are the ones that will survive, and that sometimes a good idea does not work, and what seems like a bad, even idiotic idea may actually work. This researcher shares Selberg’s view of simplicity of ideas and goes ahead to adopt sheer fraction analysis to see if the series that is the Riemann zeta function will converge to zero. Proof of the Riemann hypothesis is deemed to be necessary in order to clear the backlog of problems considered to be central to mathematics and scientific research. Hilbert’s address in Paris (1900) emphasizes the centrality of the Riemann hypothesis to mathematics when he notes that: INTRODUCTION The Riemann Hypothesis states that: H(s) = 0 (1) such that the non-trivial zeros of the Riemann zetafunction H(s) must lie on the critical line: s = ½ +it (2) t being any real number, i imaginary number and s …1. The Wikipedia (2010a) notes that the Riemann hypothesis is part of Hilbert’s list of 23 unsolved problems and also one of the Clay Mathematics Institute Millennium Prize Problems, and avails of suggestions by Hilbert and Polya that one way to derive the Riemann hypothesis would be to find a self-adjoint operator from the existence of which the statement on the real parts of the zeros of the zeta function would follow when one applies the criterion on real eigenvalues. This work similarly bases its origin on some attributes of electrons and quarks, to provide a quadratic system whose set of complex roots describe the set of analytic zeros s = ½ + it of the Riemann zeta function H(s). Constant (2008 ) in trying to prove the Riemann Hypothesis remarks that the infinite series can be made to be zero by finding the limits of the entire series or by finding that each term is equal to zero. Constant’s observation is relevant to this work as the work attempts to simplify the Riemann hypothesis as a series each of As soon as this proof has been successfully established, the next problem would consist in testing more exactly Riemann's infinite series for the number of primes below a given number and, especially, to decide whether the difference between the number of primes below a number x and the integral logarithm 39 Res. J. Math. Stat., 3(1): 39-44, 2011 of x does in fact become infinite of an order not greater than 1/2 in x. Further, we should determine whether the occasional condensation of prime numbers which has been noticed in counting primes is really due to those terms of Riemann's formula which depend upon the first complex zeros of the function H(s). After an exhaustive discussion of Riemann's prime number formula, perhaps we may sometime be in a position to attempt the rigorous solution of Goldbach's problem, viz., whether every integer is expressible as the sum of two positive prime numbers; and further to attack the well-known question, whether there are an infinite number of pairs of prime numbers with the difference 2, or even the more general problem, whether the linear diophantine equation ax + by + c = 0 (with given integral coefficients each prime to the others) is always solvable in prime numbers x and y. Hilbert’s address thus demands some urgency for resolving the Riemann hypothesis which will ultimately pave the way for further resolutions of other mathematical problems. The objective of this study is to provide a simple proof of the Riemann hypothesis. Specifically, the work aims at proving that the Riemann zeta function H(s) converges to zero or absolutely converges to zero for any n = 1, 2, 3,…. r2 = 1 k 1 +i − 2 m 4 (3) of the auxiliary energy equation of a second order homogenous ordinary differential equation, K standing for distance travelled by (or frequency of) a particle of m mass, suggested by Atovigba on the Google Epistemology Group (2010), which was further investigated by Atovigba and Chiawa (2010). The set of complex roots (3) is found using the mean and mean deviation approach of solving quadratic equations (Atovigba, 2010) who in his masters in mathematics education dissertation posits that the roots of the quadratic equation: a2x2 +a1x + a0 = 0 (4) could be expressed as: r1 = M − D ⎞ ⎟ r2 = M + D⎠ (5) where M is the mean of the roots and D the mean deviation of each root from M such that: MATERIALS AND METHODS D= This research was carried out between September 5, 2010 and November 5, 2010 at Benue State University Makurdi, Nigeria while researching and teaching Mathematics Methods 1. C Energy generated by spins of electrons and quarks, used simultaneously to obtain an auxiliary energy (quadratic) equation Mean and mean deviation approach of finding the zeros of the quadratic equation, which produces complex (analytic) zeros at some frequencies of the subatomic particles. The method used in proving the Riemann hypothesis is the method of convergence and absolute convergence of infinite series. To prove the hypothesis requires, firstly, to identify some phenomena which generates some complex operator or the set of analytic zeros s = ½ +it a0 a2 (6) To obtain (3), Atovigba and Chiawa (2010) adopts submissions by Fitzpatrick (2006) that frequency is synonymous with energy and that the higher the frequency then the higher the energy, (and further, that) the frequency of the quark spin is the square of the spin frequency of the electron's spin and from this is derived c2 , which makes energy E = mc for electrons and E = mc2 for quarks, where m stands for mass of particles and c speed of light. Hence, by simultaneous solution, mc = mc2, which leads to the quadratic equation mc2 - mc = 0 (or mc - mc2 = 0) whose left side is considered to be the auxiliary energy equation of a particle with mass m dependent on c as: The materials used in this research are: C M2 − E(c) = mc2 – mc (7) which is the trace of E passing through the origin P(0,0) and is parabolic (Fig. A, Appendix A) and cuts a whole host of infinite horizontal planes each of k perpendicular distance from the plane of origin, say k = 0. Thus there are infinite planes of variable k distance from the plane of origin which the electron or quark or atom or molecule has to travel through. Hence each time E (2) as first entries for the Riemann zeta-function. The set of analytic zeros (2) is adopted from the second complex solution 40 Res. J. Math.

This is because for any n the system could be fed with any t a real number, hence the series is of the type un(t). Specifically, what is required is the proof that: ∑n ∞ ∑ n Absolute convergence of the Riemann zeta function: Irrespective of the magnitude of n = 1, 2, 3, … , as t ÷4, the Riemann zeta function absolutely converges as: 1 t→ 0 ∑ ∞ −s ∞ = which concludes the proof. Convergence of the Riemann zeta function: Given the Riemann zeta function: −s 1 − − it 2 1 ⎛ − it ⎞ ⎜n ⎟ ⎜ 1 ⎟ = ⎝ n2 ⎠ RESULTS ∞ ∑ n Consequently, as t ÷4, 1/ni ÷ 0 so that (1/ni)i ÷ 0 so that (1/ni)i / n1/2 ÷ 0. Hence: we have (2) as the required complex operator which is fed into the Riemann zeta function in order to prove the Riemann Hypothesis, that is, that H(s) = 0. The Riemann zeta function is an infinite series which is treated for convergence and absolute convergence as t gets to infinity having realized that the Riemann zeta function depends on s, and s further depends on t. Lim ∞ = (9) from where the positive root (3) is obtained.

Thus absolute convergence of the Riemann zeta function takes place when: (12) 1 This can be done by taking the limit as t ÷4; and any of the two first entries: m mass of a particle, or k distance travelled, could vary in (10) such that t ÷ 4. Thus: Lim t→ ∞ un+ 1 (t ) =r<1 un (t ) The Riemann zeta function H(s) = H (1/2 + it) as an C if m is variant with k … 0 and m ÷0, then k/m ÷4, hence t ÷4. C if m is constant but moves such that k then t . Now, ∞ infinite series could be written as un (t ) = ∑n t =1 41 ⎛1 ⎞ − ⎜ + it ⎟ ⎝2 ⎠ Res. J. Math. Stat., 3(1): 39-44, 2011 which for the general term converges to 0 when t ÷4 and converges absolutely to 0 as demonstrated by letting n = 1 and n + 1 = 2. If n = 1 then: un (t ) = ⎛ 1⎞ ⎜ t⎟ ⎝n ⎠ i 1 n2 ⎛ 1⎞ ⎜ t⎟ ⎝1 ⎠ = involving n steps of complexity. Thus available heat energy E of such a system at any time t sec is E = H H(s), and when t tends towards infinity then entropy is maximized so that there is zero amount of heat available as an equilibrium state for the machine. The foregoing remarks relating the Riemann zeta function to entropy has implications for time as for isolated machines entropy never decreases but tends to increase (Wikipedia 2010b), a property that prohibits perpetual motion machines and suggests an arrow of time, and this prohibition is seen when E = H .(s) = 0 when time becomes infinite. Similarly, the findings indicate an idea of time in that, given the same (concentric) distance k but different particles or objects of mp masses (p = 1, 2, 3, …), for bodies of larger masses k tends to be negligible and hence time t tends to be negligible, while the reverse is the case for bodies of smaller masses. This may be a way to explain why the average year of planets nearer to their sun are shorter than that for planets farther away from the sun. The Riemann zeta function’s analytic zeros s are such that within the microscopic radii k = , > 0 a particle of mass m at any time t attains some speed s = ½ + it of magnitude: i 1 12 And for n + 1 = 2, un+ 1 (t ) = ⎛ 1⎞ ⎜ t⎟ ⎝n ⎠ i 1 n2 = ⎛ 1⎞ ⎜ t⎟ ⎝2 ⎠ i 1 22 Consequently, ⎧ ⎛ 1⎞ i ⎫ ⎪⎜ ⎟ ⎪ ⎪ ⎝ 2⎠ ⎪ ⎧ i⎫ ⎨ 1 ⎬ ⎪ (0) ⎪ ⎨ 1 ⎬ ⎪ 22 ⎪ ⎪ 22 ⎪ ⎪⎩ ⎪⎭ un + 1 (t ) Lim = Lim = ⎩ i ⎭ = i⎫ t → ∞ un ( t ) t→ ∞ ⎧ ⎧1 ⎫ ⎛ 1⎞ ⎨ ⎬ ⎪⎜ t ⎟ ⎪ ⎪⎝1 ⎠ ⎪ ⎩ 1⎭ ⎨ 1 ⎬ ⎪ 12 ⎪ ⎪⎩ ⎪⎭ ⎧ ⎫ ⎪ 0 ⎪ ⎨ 1⎬ ⎪⎩ 2 2 ⎪⎭ 0 = = 0< 1 1 {1} 2 s= DISCUSSION horizontal) and variable hypotenuse s = Let t stand for time in t seconds, then ∞ t→ 0 ∑n −s =0 1 ⎛ k 1⎞ +⎜ − ⎟ = 4 ⎝ m 4⎠ k m This implies that particles have their origin at some point P(0,0) but can reach frequencies that stretch to infinitely within the open ended right-angled triangular confinement of fixed base 1/2 unit and opposite variable side t. t is opposite the angle that s makes with the Thus the Riemann zeta function is absolutely convergent and actually converges to 0, which proves the hypothesis. Lim ⎛ 1⎞ 2 ⎜ ⎟ +t = ⎝ 2⎠ k (Fig. A). m This relation could be re-arranged so that k = ± m|s|, which is some form of momentum since has direction (red arrows in Fig. A) and is hence some velocity v, and can be written as k = ± m|s| = mv1 ± mv2 without contradiction as the particle started from the origin P(0,0) at which point k = 0 hence v1 = |s|1= 0 hence mv1 = 0. The findings can be used to investigate particle annihilation. For instance, when an electron and a positron collide they both get annihilated into two bosons each of zero masses such as gamma ray photons (Wikipedia, 2010c). Thus at annihilation, for any small k = , > 0 t tends to infinity thus making the zeta function to collapse to zero as proved in (14) thus indicating further that the Riemann hypothesis demonstrates that particle annihilation brings about 100% entropy. This further implies that bosons do not produce energy but cause energy entropy since they have zero mass which makes the Riemann zeta function to tend to zero. implies that for any n and time t 1 seconds, the Riemann zeta function supports any entropy theory which describes diminishing values of a measure of energy, say heat, available to a system which could diminish until it gets to the zero level after some time t seconds. Entropy is a measure of the energy not available for work in a thermodynamic process (Wikipedia, 2010b) and the system could consequently reach an equilibrium state (when the system no longer experiences change) when entropy is said to be maximized, because all information about the initial conditions of the system is lost except for the conserved variables. Suppose that H stands for heat available to a machine, then the product of H and the Riemann zeta function .(s) will guarantee amount of heat available to the system at any time t seconds, depending on the complexity of the machine 42 Res. J. Math. Stat., 3(1): 39-44, 2011 The findings present a distance-mass value for time as time t seconds is given by: The findings have educational value for providing added content and method in estimating energies of particles and levels of entropy towards an enriched the mathematics and science education curriculum. k 1 − =t m 4 CONCLUSION Thus time can be expressed as a real-valued function t of k distance and m mass such that: t = t(k,m): The research aimed at proving the Riemann hypothesis by showing that the Riemann zeta function as an infinite series sums to zero (0). Thus the most significant findings of this research is that the Riemann zeta function H(s) has been found to sum to zero (0) using infinite series convergence and absolute convergence. Among the unique findings of the research, the set of analytic zeros s = ½ + it of the Riemann zeta function is obtained from the pair of complex zeros of some energy equation derived from simultaneously combining masses and frequencies of electrons and quarks, which implies that the Riemann zeta function could be used to solve problems involving subatomic particles. The research findings indicate that the Riemann zeta function is a suitable factor in any entropy theory. The findings also indicate that time t depends on mass m of the particle and distance k from the origin or point of reference and that time can progress to infinity. k 1 − m 4 which, for m given, can assume an infinite value if k increases to infinity. Hence bodies that are bonded will share the same idea of time given the same reference point k (say, the sun) from their point of origin P(0,0). Time for such bonded bodies of mi masses will then be: t= 1 k − mi 4 ∑ 1 The findings thus suggest that time hence has nothing to do with a particle’s speed but everything to do with distance and the mass in view.

The particle travels cutting k variable perpendicular distance of infinite number of planes parallel to the horizontal axis through P(0,0). When the horizontal k is not tangential to the E curve, for E = k the roots are complex: c = s = ½ ±it where t= k 1 − m 4 is real and i is imaginary.
