Given a group equipped with a proper left-invariant metric, the uniform Roe algebra reflects many large-scale geometric properties of the underlying group. In this talk we study the uniform Roe algebras arising from locally finite groups. By definition, a group is locally finite if every finitely generated subgroup is finite. These are precisely the groups which are zero-dimensional in the large scale sense. It is therefore not surprising that their uniform Roe algebras exhibit very good C*-structual properties, which we will discuss.
