报告摘要：Weakly U-concordant semigroups are weakly U-abundant semigroups with (C) and U generating a regular subsemigroup whose set of idempotents is U. Following on Ehresmann-Schein-Nambooripad theorem (ESN theorem), which established a correspondence between algebraic structures (inverse semigroups) and ordered structures (inductive groupoids), this talk looks at some recent developments of (ESN) theorem and shows a correspondence between the category of weakly U-concordant semigroups and the category of certain categories with two pre-orders, which are analogous to inductive groupoids.
