## SHORT DESCRIPTION OF SEMINAR

Stochastic flows arise naturally in statistical physics, biology, hydrodynamics, etc. and are usually used for the description of dynamics of infinitely many interacting particles moving in random media. The aim of the seminar is to discuss some important results obtained for flows generated by stochastic differential equations. We will be interested in the case where the motion of particles is not only determined by a stochastic differential equation but also depends on the mass that particles transfer. This will lead us to some unification of the theory of stochastic flows and measure-valued processes. In particular, we will discuss the following topics

stochastic flows generated by stochastic differential equations;
Brownian sheet and related stochastic calculus;
random measures;
stochastic differential equations with interactions;
evolutionary measure-valued processes;
integrals with respect to random measures and equations driven by a random measure;
weak compactness and stationary measure-valued processes.
## REQUIRED KNOWLEDGE

The seminar requires knowledge of standard courses on stochastic processes. However, we also kindly invite students who have taken only the probability theory course. Since the topic of the seminar is quite wide, we will try to propose topics for the presentation that will correspond to the level of speakers. The list of topics will be offered approximately one week after the end of the registration.
