Abstract
This is a continuation and also a supplement of the previous papers [5], [6] and [8] concerning orthodox semigroups1). In [8], it has been shown that a quasi-inverse semigroup is isomorphic to a subdirect product of a left inverse semigroup and a right inverse semigroup. In this paper, we present a structure theorem for quasi-inverse semigroups and some relevant matters.
