讲座内容简介：

We study the structure of finite groups G having the same element orders as a finite simple classical group L. With a few exceptions, such a group G has a unique nonabelian composition factor S, and our primary goal is to prove that this factor is isomorphic to L. There are some particular cases of this problem that are easy if the dimension of L is sufficiently large and considerably harder if it is small (for example, the case when S is an exceptional group of Lie type).

In the talk, we discuss these cases and the ways to handle them.
