Title: | Semi-invariants and weights of group algebras of finite groups | Authors: | Passman, DS WAUTERS, Paul |
Issue Date: | 1999 | Publisher: | AMER MATHEMATICAL SOC | Source: | PROCEEDINGS OF THE AMERICAN MATHEMATICAL SOCIETY, 127(5). p. 1323-1329 | Abstract: | We study the semi-invariants and weights of a group algebra K[G] over a field K of characteristic zero. Specifically, we show that certain basic results which hold when G is a polycyclic-by-finite group with Delta(+) (G) = 1 need not hold in the case of group algebras of finite groups. This turns out to be a purely group theoretic question about the existence of class preserving automorphisms. | Notes: | Univ Wisconsin, Dept Math, Madison, WI 53706 USA.
