文摘
We say that a complex valued function defined on an Abelian group?G is a local polynomial, if its restriction to every finitely generated subgroup of?G is a polynomial. We prove that local spectral synthesis (that is, spectral synthesis using local polynomials instead of polynomials) holds on every Abelian group having countable torsion free rank. More precisely, there is a cardinal ω 1?em class="a-plus-plus">κ? ω such that local spectral synthesis holds on an Abelian group?G if and only if the torsion free rank of?G is less than?κ.
