We consider the class of Banach algebras A for which there exists a continuous homomorphism omega : L (1) (S) -> A with dense range. We study the behavior of the radical in such algebras. As an application, we present some results concerning the structure of weakly compact homomorphisms of semigroup algebras.eninfo:eu-repo/semantics/closedAccessSemigroupRepresentation SemigroupBanach AlgebraRadicalWeakly Compact HomomorphismArticle1653-4Q2Q2413432WOS:000300778600008
