Abstract

The main result of this paper is that for every locally compact abelian group G, which is not compact, the convolution algebra L1(G) contains a closed ideal which is not finitely generated. This gives a negative solution to the principal ideal problem in group algebras, which has been open for some time [5, p. 352; 6, p. 38] and [8, p. 154].
