چکیده
• Capital letters represent matrices and bold lower-case letters represent vectors. For a matrix A, aij denotes the element in row i and column j; for the vector x, xi denotes the i th entry in the vector. • Various special matrices are represented by the following conventions: The adjacency matrix is denoted A; the degree matrix is denoted D; the Laplacian D − A is denoted L. The Laplacian can be written as: ∑

Some Edge Cut Sets and an Upper bound for Edge Tenacity of Organic Compounds CnH2n+2
The graphs play an important role in our daily life. For example, the urban transport network can be represented by a graph, as the intersections are the vertices and the streets are the edges of the graph. Suppose that some edges of the graph are removed, the question arises, how damaged the graph is. There are some criteria for measuring the vulnerability of graph; the...
متن کاملAn upper bound for the regularity of powers of edge ideals
A recent result due to Ha and Van Tuyl proved that the Castelnuovo-Mumford regularity of the quotient ring $R/I(G)$ is at most matching number of $G$, denoted by match$(G)$. In this paper, we provide a generalization of this result for powers of edge ideals. More precisely, we show that for every graph $G$ and every $sgeq 1$, $${rm reg}( R/ I(G)^{s})leq (2s-1) |E(G)|^{s-1} {rm ma...

Modular invarinat, constraints the spectrum of the theory. Using the medum temprature expansion, for first and third order of derivative, a universal upper bound on the lowest primary field has been obtained in recent researches. In this paper, we will improve the upper bound on the scaling dimension of the lowest primary field. We use by the medium temprature expansion for an arbitrary orders...
متن کاملA generalized upper bound solution for bimetallic rod extrusion through arbitrarily curved dies
In this paper, an upper bound approach is used to analyze the extrusion process of bimetallic rods through arbitrarily curved dies. Based on a spherical velocity field, internal, shearing and frictional power terms are calculated. The developed upper bound solution is used for calculating the extrusion force for two types of die shapes: a conical die as a linear die profile and a streamlined di...
