Докладчик: Vitalii Konarovskyi Тема: On the existence and uniqueness of solutions to the Dean-Kawasaki equation Abstract. We consider the Dean-Kawasaki equation with smooth drift interaction potential and show that measure-valued martingale solutions exist only in certain parameter regimes in which case they are given by finite Langevin particle systems with mean-field interaction. The proof is […]

Докладчик: PD Dr. Yana Kinderknecht (Butko) (Technical University of Braunschweig) Тема: Chernoff approximation of operator semigroups generated by Markov processes Abstract: We present a method to approximate operator semigroups generated by Markov processes and, therefore, transition probabilities of these processes. This method is based on the Chernoff theorem. In some cases, Chernoff approximations provide also discrete […]
