In particular, we focus on important classes of equivalence and order relations. In the second part, we present the natural generalization of binary relations which is the n-ary relations. We focus also in this part on the ternary relations for the aim of well understanding the different generalizations of notions and proprieties from the binary to the ternary relations.frPropriétés relations binaires ternairesThesis
