Let S be an ideal of the free inverse monoid on a set X , and let B denote the Banach algebra l 1 (S). It is shown that the following statements are equivalent: B is * -primitive; B is prime; X is infinite. A similar result holds if B is replaced by C[S], the complex semigroup algebra of S. 2000 Mathematics subject classification: 43A20.
