Liouville property and Poisson boundary of random walks with infinite entropy: what's amiss?

Vadim Kaimanovich

We discuss the qualitatively new properties of random walks on groups that arise in the situation when the entropy of the step distribution is infinite.

Singularity of compound stationary measures

Behrang Forghani, Vadim Kaimanovich

We show that the product or convex combination of two Markov operators with equivalent stationary measures need not have a stationary measure from the same measure class. More spec…

Limit distributions of branching Markov chains

Vadim A. Kaimanovich, Wolfgang Woess

We study branching Markov chains on a countable state space (space of types) , with the focus on the qualitative aspects of the limit behaviour of the evolving empiric…

Amenability of groupoids and asymptotic invariance of convolution powers

Theo Bühler, Vadim A. Kaimanovich

The original definition of amenability given by von Neumann in the highly non-constructive terms of means was later recast by Day using approximately invariant probability measures…

Arboreal structures on groups and the associated boundaries

Anna Erschler, Vadim Kaimanovich

For any countable group with infinite conjugacy classes we construct a family of forests on the group. For each of them there is a random walk on the group with the property that i…

Circular slider graphs: de Bruijn, Kautz, Rauzy, lamplighters and spiders

Vadim A. Kaimanovich

We suggest a new point of view on de Bruijn graphs and their subgraphs based on using circular words rather than linear ones.
