Ivan Chajda, Šárka Hošková-Mayerová · Miskolc mathematical notes/Mathematical notes · 2005
A.By a cone of a quasiordered set (A, Q), any U Q (a) for each a ∈ A. We characterize these mappings by using certain relational inclusions.The result can be applied for construction of a quotient quasiorder hypergroup.
