2006
Publicacions matemàtiques
Preserved Fulltext
In this paper, we study the structure of group rings by means of endomorphism rings of their modules. The main tools used here, are the subrings fixed by automorphisms and the converse of Schur's lemma. Some results are obtained on fixed subrings and on primary decomposition of group rings. 2000 Mathematics Subject Classification. 16S50, 16S34.
