Large systems of oscillators in various external fields

We will consider several models of not more than countable systems of interacting particles, proposed by Vadim Aleksandrovich Malyshev, the first head of the Laboratory of Large Random Systems at the Department of Probability Theory at the Faculty of Mechanics and Mathematics. During the talk, we will examine common reactions to external forces that arise in large finite and countable systems, as well as the unusual effects that can arise when transitioning to countable systems, compared to the finite case.
