| Abstract: | We characterize finitely generated abelian semigroups such that every completely positive definite function (a function all of whose shifts are positive definite) is an integral of nonnegative miltiplicative real-valued functions (called nonnegative characters). |
| Keywords: | semigroup abelian commutative finitely generated positive definite completely positive definite character |
