About the fuzzy grade of the direct product of two hypergroupoids

Abstract

The aim of this paper is the study of the sequence of join spaces<br />and fuzzy subsets associated with a hypergroupoid. In this<br />paper we give some properties of the membership function<br />$widetildemu_{otimes}$ corresponding to the direct pro-duct of<br />two hypergroupoids and we determine the fuzzy grade of the<br />hypergroupoid $langle Htimes H, otimesrangle$ in a particular<br />case.
