Combinatorial harmonic maps and discrete-group actions on Hadamard spaces
Hiroyasu Izeki, Shin Nayatani
Abstract
We use the combinatorial harmonic map theory to study the isometric actions of discrete groups on Hadamard spaces. Given a finitely generated group acting by automorphisms, properly discontinuously and cofinitely on a simplicial complex and its isometric action on a Hadamard space, we formulate criterions for the action to have a global fixed point.
