Ds. Passman et Ae. Zalesskii, SEMIPRIMITIVITY OF GROUP-ALGEBRAS OF LOCALLY FINITE SIMPLE-GROUPS, Proceedings of the London Mathematical Society, 67, 1993, pp. 243-276
Let G be a locally finite simple group which is not a linear group. Fo
r any field K, we prove that the group algebra K[G] is semiprimitive.
The argument is almost entirely group-theoretic in nature and ultimate
ly rests upon the classification of the finite simple groups.
