From 23 to 28 September 2019 in Tula in the Tula State Pedagogical University of Leo Tolstoy will be held the XVI International Conference «Algebra, Number Theory and Discrete Geometry: modern problems, applications and problems of history», dedicated to the centenary of the birth of professor N. I. Feldman and the ninetieth anniversary of the birth of professors A. I. Vinogradov, A. V. Malyshev and B. F. Skubenko.

In the organization of the conference together with the Tula State Pedagogical University of Leo Tolstoy is attended by the Moscow State University, St. Petersburg State University, Moscow State Pedagogical University, Tula State University, Steklov Institute of Mathematics, St. Petersburg Branch of the Steklov Institute of Mathematics and Institute of History of Science and Technology of Vavilov of the Russian Academy of Sciences.

The purpose of the XV International Conference «Algebra, Number Theory and Discrete Geometry: modern problems, applications and problems of history», dedicated to the centenary of the birth of professor N. I. Feldman and the ninetieth anniversary of the birth of professors A. I. Vinogradov, A. V. Malyshev and B. F. Skubenko.

The objectives of the conference:

- the discussion of advances in algebra, number theory and discrete geometry in recent times;
- the discussion of actual research directions in algebra, number theory and discrete geometry;
- the discussion of actual fundamental problems in algebra, number theory and discrete geometry and ways to solve them.

The following sections are supposed to work at the conference:

- groups;
- semigroups and universal algebras;
- rings and modules;
- applied and computer algebra, cryptography and discrete mathematics;
- analytical number theory;
- Diophantine approximations and the theory of transcendental numbers;
- discrete geometry and geometry of numbers;
- number-theoretic method in approximate analysis and approximation theory;
- history of mathematics;
- algebraic number theory;
- arithmetic and algebraic geometry.

It is possible to include other sections in the conference program.
