Abstract: The purpose of this paper is to show that the multipliers of a special class of closed ideals in group algebras are ``trivial", and that a result of Y. Meyer for groups of the form $ {R^n} \times {T^m}$ concerning the existence of nontrivial multipliers cannot be extended to any disconnected group.
