Query: Weakly Abundant Semigroups and variants   A weakly U abundant is a class of semigroups characterized using some
generalized Green' relations. In this paper we discuss the variants of weakly U
- abundant semigroups and it is shown that the idempotent variants of these
semigroups are again weakly U abundant. Further we also discuss the natural
partial order on variants of a weakly U abundant semigroup.
