If G has a cyclic edge-cut, then it is called cyclically separable.For a cyclically separable graph G, the cyclic edge-connectivity of G, denoted by \(\lambda _{c}(G)\), is defined as the cardinality of a minimum cyclic edge-cut of G (see for …
Web4 de abr. de 2013 · In this paper info cyclic connectivity is studied in relation to certain matching properties in regular graphs. Results giving sufficient conditions in terms of cyclic connectivity for regular graphs to be factor-critical, to be 3-factor-critical, to have the restricted matching properties E(m, n) and to have defect-d matchings are obtained.
WebIn mathematics and computer science, connectivity is one of the basic concepts of graph theory: it asks for the minimum number of elements (nodes or edges) that need to be removed to separate the remaining nodes into two or more isolated subgraphs. It is closely related to the theory of network flow problems.
