Description
For a finitely generated group, one defines a graph structure, so-called Cayley graph, via a specified generating set.
For this graph, it associates with a discrete Laplace operator. The kernel of the operator consists of (discrete) harmonic functions.
Global behaviors of harmonic functions on infinite groups are of interest. In this talk, we will discuss several known results for harmonic functions on discrete groups.
