On isometries of Hardy spaces on compact abelian groups
Let Hp (m), 0 < p ^ oo, be the Hardy spaces on a quotient K of the Bohr group.In this paper we completely determine the isometries of H p {m), p Φ 2, onto itself.Our result is a generalization of a recent work of Muhly who determined the isometries …
