Realizing additive monoids as mapping degree sets
Cristina Costoya, Vicente Muñoz, Bruno Valverde-Morales +1
The paper proves that mapping degree sets are stable under multiplication by finite integer subsets containing 0 and under operations derived from additive submonoids of ℤ, and sho…
Rigidifying simplicial complexes and realizing group actions
Cristina Costoya, Rafael Gomes, Antonio Viruel
We show that any action of a finite group on a finitely presentable group arises as the action of the group of self-homotopy equivalences of a space on its fundamental group. In do…
Path partial groups
Antonio DÃaz Ramos, Rémi Molinier, Antonio Viruel
It is well known that not every finite group arises as the full automorphism group of some group. Here we show that the situation is dramatically different when considering the cat…
