RT preprint T1 Purely infinite simple skew group rings A1 Louly, A. A1 Pardo Espino, Enrique A2 Matemáticas K1 Skew group ring K1 Purely infinite simple ring AB In this note we prove that, if R is a purely infinite simple unital ring, G is a group, and α : G → Aut(R) is an outer action on R, then the skew group ring R∗α G is a purely infinite simple ring YR 2014 FD 2014-04-21T00:00:00Z LK http://hdl.handle.net/10498/16138 UL http://hdl.handle.net/10498/16138 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 13-nov-2026
