Abstract
We construct a simple example, surely known to Harry Kesten, of an R-transient Markov chain on a countable state space S with cemetery state delta. The transition matrix K on S is irreducible and strictly substochastic. We determine the Yaglom limit, that is, the limiting conditional behavior given non-absorption. Each starting state x in S results in a different Yaglom limit. Each Yaglom limit is an rho-invariant quasi-stationary distribution where rho=1/R and R is the convergence parameter of . Yaglom limits that depend on the starting state are related to a nontrivial rho-Martin entrance boundary.
