M_λ ipergruppoidi matroidali. Applicazioni λ-lineari e automorfismi di M_λ-ipergruppoidi
In this paper we forward in the investigation of the matroidal <em>M_λ</em> -hypergrupoids introduced in [13]. We give necessary and sufficient conditions for such hypergrupoid to be matroidal; moreover, we find its cardinality and we analyse the properties of the corresponding omomorphi...
