Abstract:
We suggest a new method for describing invariant measures on Markov compacta and on path spaces of graphs and, thereby, for describing characters of certain groups and traces of $AF$-algebras. The method relies on properties of filtrations associated with a graph and, in particular, on the notion of a standard filtration. The main tool is an intrinsic metric introduced on simplices of measures; this is an iterated Kantorovich metric, and the central result is that the relative compactness in this metric guarantees the possibility of a constructive enumeration
of ergodic invariant measures. Applications include a number of classical theorems on invariant measures.
Keywords:
invariant and central measures, projective limit of simplices, filtrations, intrinsic metric, uniform compactness.
