报告摘要  Abstract

A permutation group is called synchronizing if the semigroup generated by the group together with any non-permutation of the domain contains an element of rank 1 (that is, whose image consists of a single point). This concept arose in automata theory. The definition can be translated to one involving graph endomorphisms. I will outline what is known about synchronizing groups.
