报告摘要：In this talk, I will introduce verbally closed subgroups of groups. These subgroups come from studying algebraic geometry over groups. I will sketch a proof given by A. Myasnikov and V. Roman’kov that every verbally closed subgroup of a free group F of finite rank is a retract and then describe some potential research on this topic.
