Title

The Schützenberger Group of an H-class in the Semigroup of Binary Relations

Abstract

K. A. Zaretskii has associated a lattice V(α) with each binary relation α, and he has shown that Hα is isomorphic with the group of all automorphisms of V(α) if Hα is a group. This result is extended in this paper by showing that for any binary relation α, the Schützenberger group Γ (Hα) is isomorphic with the group of all automorphisms of V(α).
