Topological types of Klein surfaces with a maximum order automorphism

AUTOMORPHISM GROUP OF GROUPS OF ORDER pqr

H"{o}lder in 1893 characterized all groups of order $pqr$ where  $p>q>r$ are prime numbers. In this paper,  by using new presentations of these groups, we compute their full automorphism group.

Topological Complexity of Basis-conjugating Automorphism Groups

We compute the topological complexity of Eilenberg-MacLane spaces associated to the group of automorphisms of a finitely generated free group which act by conjugation on a given basis, and to certain subgroups.
