Abstract
LetG be a locally compact abelian group and Γ its dual group. For any closedH ⊆G denote the algebra of restrictions toH of Fourier transforms of functions inL 1(Γ) byA(H). This paper considers certain Cantor like sets inR and ΠZ m(j) and gives some necessary algebraic criterion fornatural isomorphisms of their restriction algebras.
