Non-singly-generated closed ideals in group algebras

Research output: Contribution to journalArticlepeer-review


We investigate the problem whether every closed ideal in the group algebras A(G) is generated by a single function. For the algebras Ar(Rn), n≧6, we give a negative solution. We also obtain some negative results for general locally compact abelian groups.
