We use Sigma-invariants to study homotopical and homological finiteness properties of fixed subgroups of automorphisms of a group G in terms of its center Z (G) and the induced automorphisms on its associated quotient G/Z (G). Specializing to the case where the center is a direct factor of the group, we answer a question made by Lei, Ma and Zhang.
Almeida et al. (Wed,) studied this question.
