On base radical and semisimple operators for a class of finite algebras

  • L. K. Thornton
Original Paper


In this paper we determine the base radical and semisimple class operators for universal classes in a finite setting using algebras introduced by Puzcyłowski. The six possible orders for the semigroup they form are at most 14. A complete listing of base radical and semisimple operators for a number of different universal classes is provided.
