Seminar 31.10.2023

Speaker: Oleksii Rudenko (Institute of Mathematics of NAS of Ukraine) Topic: Multiple intersections and potentials for several independent Brownian motions in Carnot groups Abstract: It is well-known that a hitting probability of Markov process can be represented as a potential of some measure. Moreover there are several results relating the probability for the product of trajectories of several independent […]

Seminar 17.10.2023

Speaker: Mykola Vovchanskyi (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. […]
