The program is intended for lecturers teaching this course, course assistants and students of 01.04.01 specialization «Mathematics» who study the course “Introduction to Number Theory ”. 2 The program has been elaborated in accordance with the Educational standard of HSE for training area 01.04.01 «Mathematics» (Master level); In accordance with the working studying plan of the university for training area of 01.04.01 specialization «Mathematics» (Master level), master program “Mathematics”, approved in 2014. Learning objectives Studying the course “Introduction to Number Theory ” aims at making the students familiar with the main examples, constructions and techniques of the theory of infinite dimensional Lie algebras with applications in mathematical physics. In particular, the students will learn the basics of the theory of vertex operator algebras, playing the crucial role in the modern mathematical language of the quantum filed theory. Course goals: 3 To make students familiar with the simpler examples of the Diophantine questions. To describe the Hasse principle via the example of quadratic form in two variables. To study the Quadratic reciprocity and perform computation of the Legendre symbols. To make clear the role of the Riemann zeta function and the Dirichlet L-functions in arithmetic geometry. To educate students about major concepts in algebraic number theory. To expose students to various broad subjects in number theory. Learning outcomes By the end of the course student is supposed to 4 Know: The basic concepts in algebra and algebraic number theory such as zeta functions, local and global fields. Be able to: Understand some basic terminology in modern number theory. Read without help the more advanced texts aimed at graduate students. Solve or perform example computations when given problems in number theory. Place of Discipline in MA program structure This course is a professional one.

He/she needs to meet the requirement to be eligible to take the examinations. The resulting grade for the final evaluation in the form of examination is calculated according to this formula (where Оэкзамен is the evaluation of the student’s performance at the exam itself): Оитоговый = 0,8·Оэкзамен + 0,2·Отекущий This grade which is the resulting grade for the course is written down in the student’s certificate (diploma).
