In graph theory, abridge,isthmus,cut-edge, orcut arcis an edge of a graph whose deletion increases its number of connected components. Equivalently, an edge is a bridge if and only if it is not contained in any cycle. A graph is said to bebridgelessoristhmus-freeif it contains no brid...
A balloon in a graph G is a maximal 2-edge-connected subgraph incident to exactly one cut-edge of G. Let b(G) be the number of balloons, let c(G) be the number of cut-edges, and let α′(G) be the maximum size of a matching. Let , we prove the sharp inequalities c(G)...
the act of penetrating or opening open with a sharp edge; "his cut in the lining revealed the hidden jewels" noun the act of reducing the amount or number; "the mayor proposed extensive cuts in the city budget" noun the act of shortening something by chopping off the ends; "the ...
is fashioned in. I like the cut of that suit. Shakespeare with eyes severe and beard of formal cut A slab, especially of meat. That’s our finest cut of meat. (fencing) An attack made with a chopping motion of the blade, landing with its edge or point. A deliberate snub, ...
The reason for this is simple: in a cut, for every edge A-B you must cut either s-A or B-t, so necessarily the set of edges you cut form a valid vertex cover. → Reply Crying 23 months ago, # | +8 I'm bad in graph theory like that. To me,this tutorial is a very ...
Lovász-Schrijver PSD-Operator on Some Graph Classes Defined by Clique Cutsets This work is devoted to the study of the Lovász-Schrijver PSD-operator [equation] applied to the edge relaxation [equation] of the stable set polytope [equation] of a graph G. In order to... Annegret K. Wagle...
This concept is closely related to the emerging field of graph norms, and the notions of the step Sidorenko property and the step forcing property introduced by Král, Martins, Pach and Wrochna [The step Sidorenko property and non-norming edge-transitive graphs, J. Combin. Theory Ser. A 162...
1) principal cut edge 主割边1. Applying the theory of the cut edge and connectivity concerning non directed graph in the graph theory,this paper deals with the concept of the principal cut edge and secondary connectivity,derives several related properties,and puts forward an effective method to ...
