Abstract: Let $ K[G]$ denote the group ring of $ G$ over the field $ K$ of characteristic $ p > 0$. An interesting unsolved problem is to find necessary and sufficient conditions on $ G$ for $ K[G]$ to be semisimple. Even the special case in which $ G$ is assumed to be a solvable group is still open. In this paper we prove a number of theorems which may be of use in this special case.
