Integral Group Rings of Finite Groups of Lie Type

Bulletin of the London Mathematical Society, 1999
The isomorphism problem for integral group rings, which is the question whether for two groups \(G\) and \(H\), \(\mathbb{Z} G\cong\mathbb{Z} H\) implies \(G\cong H\), is studied for certain finite groups of Lie type. Namely, if \(\mathbb{G}\) is a simply connected simple algebraic group over an algebraically closed field \(k\) of positive ...

Automorphisms and isomorphisms of integral group rings of finite groups

1984
This talk presented a preliminary version of joint work with L.L.Scott on the isomorphism problem for finite groups. Since a detailed version of the results is going to appear in Proceedings Groups — Korea 1983, I shall here only state the main results.
