Occupation laws for some time-nonhomogeneous Markov chains

We consider finite-state time-nonhomogeneous Markov chains whose transition matrix at time n is I + G/nζ where G is a “generator” matrix, that is G(i, j) > 0 for i, j distinct, and G(i, i) = − ∑ k 6=iG(i, k), and ζ > 0 is a strength parameter. In these chains, as time grows, the positions are less and less likely to change, and so form simple models of age-dependent time-reinforcing schemes. Th...

Moderate Deviations for Time-varying Dynamic Systems Driven by Nonhomogeneous Markov Chains with Two-time Scales∗

Motivated by problems arising in time-dependent queues and dynamic systems with random environment, this work develops moderate deviations principles for dynamic systems driven by a fast-varying nonhomogeneous Markov chain in continuous time. A distinct feature is that the Markov chain is time dependent or inhomogeneous so are the dynamic systems. Under irreducibility of the nonhomogeneous Mark...

Stopped Markov chains with stationary occupation times

Let E be a nite set equipped with a group G of bijective transformations and suppose that X is an irreducible Markov chain on E that is equivariant under the action of G. In particular, if E = G with the corresponding transformations being left or right multiplication, then X is a random walk on G. We show that when X is started at a xed point there is a stopping time U such that the distributi...

Large Deviations for a Class of Nonhomogeneous Markov Chains

Large deviation results are given for a class of perturbed non-homogeneous Markov chains on finite state space which formally includes some stochastic optimization algorithms. Specifically, let {Pn} be a sequence of transition matrices on a finite state space which converge to a limit transition matrix P. Let {Xn} be the associated non-homogeneous Markov chain where Pn controls movement from ti...
