Miha Brešar: Subexponential lower bounds for ergodic Markov processes

V četrtek, 21. 12. 2023, ob 14:15 bo v predavalnici 2.04 v okviru seminarja VeSFiM potekalo predavanja Mihe Brešarja (U. of Warwick) z naslovom: Subexponential lower bounds for ergodic Markov processes.

Povzetek: We discuss a novel criterion for establishing lower bounds on the rate of convergence towards the invariant distribution of a continuous Markov process. Our approach centers around identifying certain super/submartingale properties of functionals of the Markov process. This contribution complements the existing literature on the Lyapunov function approach to the stability of Markov processes, which primarily focuses on upper bounds. We apply these results to classical models in stochastic stability theory and show asymptotic optimality of our results. This is joint work with A. Mijatović.
