Seminar 20.02.2024
Speaker: Oleksii Rudenko (Institute of Mathematics of NAS of Ukraine) Topic: Integrability properties for densities of Brownian motions in Carnot group Abstract. We consider transition densities for Brownian motions in Carnot group and for some other types of Markov processes. Using known results regarding estimates of such densities we are going to present necessary and sufficient conditions for finiteness of some integrals, […]

Seminar 19.12.2023
Speaker: Mykola Vovchanskii (Institute of Mathematics of NAS of Ukraine) Topic: On operator splitting methods for stochastic flows: dual non-homeomorphic flows, error expansions Abstract: A splitting scheme for 1d stochastic flows is revisited. Two quite separate questions are addressed. The first one concerns non-homeomorphic flows and deals with the convergence of dual flows evolving in the reversed time. The […]
