Approximation of SDEs -- a stochastic sewing approach

Oleg Butkovsky, Konstantinos Dareiotis, Máté Gerencsér

We give a new take on the error analysis of approximations of stochastic differential equations (SDEs), utilizing and developing the stochastic sewing lemma of Lê (2020). This appr…

Couplings via comparison principle and exponential ergodicity of SPDEs in the hypoelliptic setting

Oleg Butkovsky, Michael Scheutzow

We develop a general framework for studying ergodicity of order-preserving Markov semigroups. We establish natural and in a certain sense optimal conditions for existence and uniqu…
