Partial orders on partial Baer-Levi semigroups
Marques-Smith and Sullivan [Partial orders on transformation semigroups, Monatsh. Math. 140 (2003), 103-118] studied various properties of two partial orders on P(X), the semigroup (under composition) consisting of all partial transformations of an arbitrary set X. One partial order was the containm...
