Abstract

We introduce and study dynamical systems and measures on stationary generalized Bratteli diagrams BB that are represented as the union of countably many classical Pascal-Bratteli diagrams. We describe all ergodic tail invariant measures on BB. For every probability tail invariant measure νp\nu_p on the classical Pascal-Bratteli diagram, we approximate the support of νp\nu_p by the path space of a subdiagram. By considering various orders on the edges of BB, we define dynamical systems with various properties. We show that there exist orders such that the sets of infinite maximal and infinite minimal paths are empty. This implies that the corresponding Vershik map is a homeomorphism. We also describe orders on both BB and the classical Pascal-Bratteli diagram that generate either uncountably many minimal infinite and uncountably many maximal infinite paths, or uncountably many minimal infinite paths alongside countably infinitely many maximal infinite paths.
