Abstract
In this paper we are concerned with longtime behavior of EulerMaruyama schemes associated with regimeswitching diffusion processes The key contributions of this paper lie in that existence and uniqueness of numerical invariant measures are addressed i for regimeswitching diffusion processes with finite state spaces by the PerronFrobenius theorem if the “averaging condition” holds and for the case of reversible Markov chain via the principal eigenvalue approach provided that the principal eigenvalue is positive ii for regimeswitching diffusion processes with countable state spaces by means of a finite partition method and an MMatrix theory We also reveal that numerical invariant measures converge in the Wasserstein metric to the underlying ones Several examples are constructed to demonstrate our theory
