Abstract:

Two theorems showing the existence of primitive group rings are proved. Theorem 1. Let G be a countable locally finite group and F a field of characteristic 0, or characteristic p if G has no elements of order p. Then the group ring $F[G]$ is primitive if and only if G has no finite normal subgroups. Theorem 2. Let G be any group, and F a field. Then there is a group H containing G such that $F[H]$ is a primitive ring.
