| Abstract: | In this paper we seek to determine the Jacobson radical of certain algebras based on semigroups, and in particular on the semigroups (βS,□), where S is a cancellative, countable, abelian semigroup and βS is its Stone–?ech semigroup compactification. In particular, we wish to determine the radical of ? ?1(β?). |
