Invariant measures and Markov chains with random transition probabilities
Invariant measures Markov chains random transition probabilities

In this paper, suTTicient conditions for the existence of
(a-finite) invariant measures for a class of Markov chains with random
transition probabilities are given. A special class of Markov chains

Small time expansions for transition probabilities of some Lévy processes
Lévy process transition probabilit
2009/4/29
We show that there exist Lévy processes (X_t,t ≥ 0) and reals y>0 such that for small t, the probability P(X_t> y) has an expansion involving fractional powers or more general functions of t. This con...
