A note on surjunctive groups

Abstract

In this article, we prove that a semidirect product of a locally finite group with a surjunctive group is also surjunctive. We also prove that a surjunctive-by-locally finite group is again surjunctive.

Professor Gulnara Arzhantseva mentioned me that the main result of this article is already proved by them in arXiv:1312.7682
