Abstract:
Groups are said to be isospectral if they have the same sets of element orders. Suppose that $L$ is a finite simple linear or unitary group of dimension 4 over a field of odd characteristic. We prove that every finite group isospectral to $L$ is an almost simple group with socle $L$.
Keywords:
simple classical group, element order, recognition by spectrum.
