Algebra

# Algebra

• Omar Khayyam
Omar Khayyám ; born Ghiyāth ad-Dīn Abu'l-Fatḥ ʿUmar ibn Ibrāhīm al-Khayyām Nīshāpūrī (/ˈoʊmɑːr kaɪˈjɑːm, -ˈjæm, ˈoʊmər/; Persian: غیاث‌الدین ابوالفتح عمر ابراهیم خیام نیشابورﻯ‎‎, pronounced [xæjˈjɑːm]; 18 May 1048 – 4 December 1131), was a Persian mathematician, astronomer, philosopher, and poet, widely considered to be one of the most influential thinkers of the Middle Ages.
• Operator (mathematics)
An operator is a mapping from one vector space or module to another.
• Elementary algebra
Elementary algebra encompasses some of the basic concepts of algebra, one of the main branches of mathematics.
• Group representation
In the mathematical field of representation theory, group representations describe abstract groups in terms of linear transformations of vector spaces; in particular, they can be used to represent group elements as matrices so that the group operation can be represented by matrix multiplication.
• Filtration (mathematics)
In mathematics, a filtration is an indexed set Si of subobjects of a given algebraic structure S, with the index i running over some index set I that is a totally ordered set, subject to the condition that if i ≤ j in I, then Si ⊆ Sj.
• Factorization of polynomials
In mathematics and computer algebra, factorization of polynomials or polynomial factorization is the process of expressing a polynomial with coefficients in a given field or in the integers as the product of irreducible factors with coefficients in the same domain.
• Outline of algebra
The following outline is provided as an overview of and topical guide to algebra: Algebra is one of the main branches of mathematics.
• Primitive part and content
In algebra, the content of a polynomial with integer coefficients (or, more generally, with coefficients in a unique factorization domain) is the greatest common divisor of its coefficients.
• Algebraic integer
In Algebraic number theory, an algebraic integer is a complex number that is a root of some monic polynomial (a polynomial whose leading coefficient is 1) with coefficients in (the set of integers).
• Boolean algebra
In mathematics and mathematical logic, Boolean algebra is the branch of algebra in which the values of the variables are the truth values true and false, usually denoted 1 and 0 respectively.
• Determinant
In linear algebra, the determinant is a useful value that can be computed from the elements of a square matrix.
• Goursat's lemma
Goursat's lemma, named after the French mathematician Édouard Goursat, is an algebraic theorem about subgroups of the direct product of two groups.
• Gelfand–Naimark theorem
In mathematics, the Gelfand–Naimark theorem states that an arbitrary C*-algebra A is isometrically *-isomorphic to a C*-algebra of bounded operators on a Hilbert space.
• Operand
In mathematics, an operand is the object of a mathematical operation, a quantity on which an operation is performed.
• New algebra
The new algebra or symbolic analysis is a formalization of algebra promoted by François Viète in 1591 and by his successors after 1603.
• Algebra
Algebra (from Arabic "al-jabr" meaning "reunion of broken parts") is one of the broad parts of mathematics, together with number theory, geometry and analysis.
• Moderne Algebra
Moderne Algebra is a two-volume German textbook on graduate abstract algebra by Bartel Leendert van der Waerden (, ), originally based on lectures given by Emil Artin in 1926 and by Emmy Noether () from 1924 to 1928.
• Closed-form expression
In mathematics, a closed-form expression is a mathematical expression that can be evaluated in a finite number of operations.
• Square (algebra)
In mathematics, a square is the result of multiplying a number by itself.
• Algebraic solution
An algebraic solution or solution in radicals is a closed form expression, and more specifically a closed-form algebraic expression, that is the solution of an algebraic equation in terms of the coefficients, relying only on addition, subtraction, multiplication, division, raising to integer powers, and the extraction of nth roots (square roots, cube roots, and other integer roots).
• Exponentiation
Exponentiation is a mathematical operation, written as bn, involving two numbers, the base b and the exponent n.
• Partial fraction decomposition
In algebra, the partial fraction decomposition or partial fraction expansion of a rational function (that is a fraction such that the numerator and the denominator are both polynomials) is the operation that consists in expressing the fraction as a sum of a polynomial (possibly zero) and one or several fractions with a simpler denominator.
• Nth root
In mathematics, an nth root of a number x, where n is usually assumed to be a positive integer, is a number r which, when raised to the power n yields x where n is the degree of the root.
