T1 - Moments for stationary Markov chains with asymptotically zero drift
AU - Korshunov, Dmitry
PY - 2011/7
Y1 - 2011/7
N2 - We consider a Markov chain on ℝ+ with asymptotically zero drift and finite second moments of jumps. We assume that the chain has invariant distribution. The paper is devoted to the existence and nonexistence of moments of invariant distribution. Our analysis is based on the technique of test functions.
