Sur les hypergroupoides résidués généralisés. (On the generalized residuated hypergroupoids)
The author studies a generalization of the concept of residuated hypergroupoid introduced by herself in a preceding paper. This concept is a multivalued interpretation of the axioms of resi\(=\{f(x): \| x\| =1\}.\) It is known that \(W\) is convex when \(n\geq 3\) and \(m=3\), and \(W\) is not convex in general when \(m>3\). The authors give geometric proofs of these results and study the geometry of \(W\).
