Abstract

For a CC^{*}-category with a strict GG-action we construct examples of equivariant coarse homology theories. To this end we first introduce versions of Roe categories of objects in CC^{*}-categories which are controlled over bornological coarse spaces, and then apply a homological functor. These equivariant coarse homology theories are then employed to verify that certain functors on the orbit category are CP-functors. This fact has consequences for the injectivity of assembly maps.
