MQFT is a biennially held international conference this year dedicated to the 82nd anniversary of professor Alexander Nikolaevich Vasiliev (1940-2006) and 80th anniversary of professor Vladimir Dmitrievich Lyakhovsky (1942-2020). From year to year, the conference attracts the most distinguished members of the world-famous centres for theoretical physics. The main topics of the conference are related to the most actual and important problems related to the construction and investigation of the quantum field theory models. During the conference, it is proposed to discuss the modern methods of QFT and applications of these methods to the elementary particle physics and statistical physics, gravitation and cosmology, mathematical problems and methods in quantum field theory, and integrable models.
