WebSep 4, 2024 · Video explains the concept of Transitive Closure of a Relation/ digraph For any relation R, the transitive closure of R always exists. To see this, note that the intersection of any family of transitive relations is again transitive. Furthermore, there exists at least one transitive relation containing R, namely the trivial one: X × X. The transitive closure of R is then given by the intersection of all transitive relations containing R. For finite sets, we can construct the transitive closure step by step, starting from R and adding tr…

WebDec 6, 2014 · If R is already transitive, then R = R +. So a transitive closure is also a relation, and it is the relation that is obtained by expanding the original relation in such a way as to make it transitive.

WebIn Annals of Discrete Mathematics, 1995 Proof. We regard P as a set of ordered pairs and begin by finding pairs that must be put into L1 or L2. First of all, L1 must contain the transitive closure of P ∪ R1 and L2 must contain the transitive closure of P ∪ R2. Hence we put Pi = P ∪ Ri for i = 1, 2 and replace each Pi by its transitive closure.
