Centralizers and classifying spaces for commutativity of $S{L}_2(\mathbb{Z}[1/p])$

Omar Antol\'ın-Camarena, Ramón Flores, Luis Jorge Sánchez Saldaña

We compute the homotopy type of the classifying space for commutativity introduced by Adem, F. Cohen and Torres-Giese for the group $\SL_2(\Z[1/p])$, both as a discrete topological…
