ON THE MATCHING NUMBER OF AN UNCERTAIN GRAPH

, 2017
Summary: Uncertain graphs are employed to describe graph models with indeterministic information that produced by human beings. This paper aims to study the maximum matching problem in uncertain graphs. The number of edges of a maximum matching in a graph is called matching number of the graph.

An improved lower bound for the nullity of a graph in terms of matching number

Linear and multilinear algebra, 2020
Let G be a connected undirected graph without loops and multiple edges. By , and we, respectively, denote the order, the nullity, and the matching number of G. Let , and let be a nonnegative integer defined as: To make G to be a bipartite connected graph

On the relation between the adjacency rank of a complex unit gain graph and the matching number of its underlying graph

Linear and multilinear algebra, 2020
Let be an n-vertex complex unit gain graph and let G be its underlying graph. The adjacency rank of , written as , is the rank of its adjacency matrix and denote by the matching number of the underlying graph G.

The Kirchhoff index and the matching number

International Journal of Quantum Chemistry, 2008
AbstractThe Kirchhoff index of a connected (molecular) graph is the sum of the resistance‐distances between all unordered pairs of vertices and may also be expressed by its Laplacian eigenvalues. We determine the minimum Kirchhoff index of connected (molecular) graphs in terms of the number of vertices and matching number and characterize the unique ...

Relationship between the rank and the matching number of a graph

Applied Mathematics and Computation, 2019
Given a simple graph G, let A(G) be its adjacency matrix and α′(G) be its matching number. The rank of G, written as r(G), refers to the rank of A(G). In this paper, some relations between the rank and the matching number of a graph are studied. Firstly,

On Neighbourhood Matching for Texture‐by‐Numbers

Computer Graphics Forum, 2010
Abstract Texture‐by‐Numbers is an attractive texture synthesis framework, because it is able to cope with non‐homogeneous texture exemplars, and provides the user with intuitive creative control over the outcome of the synthesis process. Like many other exemplar‐based texture synthesis methods, its basic underlying mechanism is neighbourhood matching ...

Matching number, connectivity and eigenvalues of distance signless Laplacians

Linear and multilinear algebra, 2019
Let G be a connected graph. The first and the second largest distance signless Laplacian eigenvalues of G are denoted by and . In this paper, we determine the graphs with the minimum among n-vertex graphs with given matching number.

The fractional matching numbers of graphs

Networks, 2002
AbstractA fractional matching of a graph G is a function f that assigns to each edge a number in [0, 1] such that, for each vertex v, ∑ f(e) ≤ 1, where the sum is taken over all edges incident to v. The fractional matching number of G is the supremum of ∑e∈E(G) f(e) over all fractional matchings f.

Fractional matching number and eigenvalues of a graph

Linear and multilinear algebra, 2018
A fractional matching of a graph G is a function f giving each edge a number in so that for each , where is the set of edges incident to v. The fractional matching number of G, written , is the maximum of over all fractional matchings.
