报告摘要:The normalizer problem of integral group rings has been studied extensively in recent years due to its connection with the longstanding isomorphism problem of integral group rings. Class-preserving Coleman automorphisms of finite groups occur naturally in the study of the normalizer problem. The aim of thistalk is to investigate class-preserving Coleman automorphisms of some classes of finite groups without any restrictions on the structure of Sylow 2-subgroups. As direct consequences, the normalizer problem has a positive answer for such groups.
