The tenacity of a graph
Webtenacity, rupture degree and edge-analogues of some of them. Among these parame-ters, the tenacity and rupture degree are two better ones to measure the stability of a network. In this paper we consider two extremal problems on the tenacity of graphs: Determine the minimum and maximum tenacity of graphs with given order and size. WebMay 1, 2005 · Formally, the edge-tenacity of a graph G is defined as T′ (G)=min sc (S), where the minimum is taken over all edge-sets S of G. A subset S of E (G) is said to be a T′-set of …

WebJan 1, 2001 · The tenacity of a graph G, T(G), is defined by T(G)=min{ S +τ(G−S)ω(G−S)}, where the minimum is taken over all vertex cutsets S of V(G), ω(G−S) is the number of … WebIn the 1970s, Richard Stanley introduced the notion of reciprocity for pairs of combinatorial polynomials. We show that, in a considerable number of cases, there is a polynomial in the reciprocal relation to the cycle polynomial of G; this is the orbital chromatic polynomial of Γ and G, where Γ is a G-invariant graph, introduced by the first author, Jackson and Rudd.
WebSep 2, 1999 · These desirable properties of networks can be measured by various parameters like connectivity, toughness, integrity, and tenacity.

In 1965, scientists at DuPont discovered a new method of producing an almost perfect polymer chain extension. The polymer poly-p-benzamide was found to form liquid crystalline solutions due to the simple repetitiveness of its molecular backbone.
WebThe tenacity of a graph is a measure of the vulnerabil-ity of a graph. In this paper we investigate a refinement that in-volves the neighbor isolated version of this parameter. WebApr 1, 2015 · Abstract. It is well known that the tenacity is a proper measure for studying vulnerability and reliability in graphs. Here, a modified edge-tenacity of a graph is …
WebThe first-order edge-tenacity T 1 ( G ) of a graph G is defined as T 1 ( G ) = m i n { X + ( G - X ) ω ( G - X ) - 1 } where the minimum is taken over every edge-cutset X that separates G into ω ( G - X ) components, and by ( G - X ) we denote the ... bret baier son healthWebThe meaning of TENACITY is the quality or state of being tenacious.
