Abstract
Abel-Grassmann's groupoids or shortly AG-groupoids have been studied in a number of papers, although under different names. In some papers they are named LA-semigroups, in other left invertive groupoids. In this paper we introduce a notion of kernel normal system of inverse AG**-groupoids and introduce congruences, in a similar way as that have been defined for inverse semigroups.Fulltext
