“Infrared modifications of gravitation theories”
February - April, 2020
During the visit of Mikhail S. Volkov, Doctor of physical and mathematical sciences, professor at the Université de Tours (France) to the ITMP, there was given a course of lectures named “Infrared modifications of gravitation theories” for students of Master’s program “Quantum Gravity and Mathematical Physics”. The main focus of this course was on the mathematical constructions and methods used in constructing various modifications of gravity, as well as on the theoretical description of alternative models. In addition, there was given an overview of the experimental constraint currently existing in this area.

"Hamiltonian Mechanics and Classical Integrable Systems”
February - Aril, 2020
The objective of the present elective course is to introduce the students to the main directions of the theory of integrable systems and related problems. In classical mechanics, integrable systems were described as the reduction ultimation of unrestricted motion in the symmetry group. At the same time, the Lax equations standard forms and r-matrix structures were introduced, and basic examples were considered. Non-autonomous generalizations of integrable systems were connected with the Painleve equations and the Schlesinger systems in a natural way. It was also planned to explain how solitonic equations and 1 + 1 integrable hierarchies begin. There was made an introduction to quantum exactly soluble modelsat the end of the course. Their prime tool is a quantum R-matrix and RTT-relations, and it solves the problem of quantizing groups and Lie algebras.

“Gravity and Quantum mechanics: is it supreme crisis in current physics?”
October 08, 2019
Marc Henneaux is a famous theoretical physicist, professor at the Free University of Brussels, International Solvay Institutes for Physics and Chemistry Director, professor at the Collège de France. He was rewarded with a number of prestigious awards including Francqui Prize, Humboldt Research Award and The Bogoliubov Prize (JINR).
The lecture contemplates revolutionary concepts underlying Einstein theory of gravity and quantum mechanics theory, the conflict origin between them and the present attempts to build their successive synthesis (the most significant of which is still string theory). The “symmetry” concept and its importance in this goal achievement were also explained.
The lecture language is English.

“A new lease on life of Quantum field theory”
June 10, 2019
Mikhail Shifman is a Soviet and American physicist celebrated for his researches in theoretical physics of high energies and in quantum chromodynamics especially. Mikhail Shifman was awarded many international prizes including the Dirac Medal.
The lecture was held at the International Conference "Modern Achievements in Theoretical Physics of Fundamental Interactions", dedicated to the opening of the Institute for Theoretical and Mathematical Physics.
Modern quantum field theory (QFT) underwent radical changes in comparison to what students study in textbooks. A number of concepts that were considered to be essential have been completely redefined. New concepts are the result from the factors of supersymmetry and string theory proper study. Strong communication mode is in the focus of current QFT attention. Presently, we witness striking revelations and achievements in the meaning of strong communication mode in condensed matter physics and in high-energy physics.

Russian and British physicist of repute Arkady A. Tseytlin made a foundational contribution to the development of superstring theory and field theory.
The lecture reviews one of the main directions of current theoretical physics – correlation between supersymmetric gauge theory and string theory in Anti-de Sitter space. Some of duality applications to the computations of the gauge theory main objects out of perturbation theory on coupling constant were considered.

“How light in weight can dark matter be and where look for it?”
March 06, 2019
Sergey is well-known expert on infra-red modification of general theory of relativity, supplementary measurements, cosmological models, quantum field theory and quantum gravity.
A well-accepted hypothesis about superlight dark matter, its relation to the string theory model, and also restrictions that can be received from observations on lightweight dark matter were discussed in the lecture.
