Abstract:

Inspired by the property of finite asymptotic dimension of Gromov, a geometric concept of finite decomposition complexity is introduced in game theoretic terms by E. Guentner, R. Tessera and G. Yu. Finite decomposition complexity is a large scale property of a metric space. It generalizes finite asymptotic dimension and applies to a wide class of groups . Here I will give some examples and prove that Thompson's group F equipped with the word-metric with respect to the infinite generating set does not have finite decomposition complexity.
