GREM-like K processes on trees with infinite depth

Abstract

We take up the issue of deriving the limit as nn\to\infty of the GREM-like K process on a tree with nn levels. Under specific conditions on the parameters of the process, implying the martingality of a modification of the underlying clock process sequences, we obtain infinite level clock processes as nontrivial limits of the finite level clocks, and use them to construct a process on a suitable product space which is then shown to be the limit of the nn level K processes as nn\to\infty. Some properties of the limiting, infinite level K process are established, like an expression for the asymptotic empirical measure of cylinders, giving information on the prospective equilibrium measure of the infinite level dynamics.
