A Note on the Spectral Radius of Weighted Signless Laplacian Matrix
Advances in Linear Algebra & Matrix Theory, 2018 A weighted graph is a graph that has a numeric label associated with each edge, called the weight of edge. In many applications, the edge weights are usually represented by nonnegative integers or square matrices. The weighted signless Laplacian matrix of a weighted graph is defined as the sum of adjacency matrix and degree matrix of same weighted ...

European Journal of Pure and Applied MathematicsA Generalized core-satellite graph Θ(c, S, η∗) belongs to the family of graphs of diameter two. It has a central core of nodes connected to a few satellites, where all satellite cliques are not identical and might be of different sizes. These graphs can be used to model any real-world complex network.

Maxima of the signless Laplacian spectral radius for planar graphs
, 2014 The signless Laplacian spectral radius of a graph is the largest eigenvalue of its signless Laplacian. In this paper, we prove that the graph $K_{2}\nabla P_{n-2}$ has the maximal signless Laplacian spectral radius among all planar graphs of order $n\geq 456$.

The Signless Laplacian Spectral Radius of Some Special Bipartite Graphs
Journal of Applied Mathematics and Physics, 2018 This paper mainly researches on the signless laplacian spectral radius of bipartite graphs Dr(m1,m2;n1,n2). We consider how the signless laplacian spectral radius of Dr(m1,m2;n1,n2) changes under some special cases. As application, we give two upper bounds on the signless laplacian spectral radius of Dr(m1,m2;n1,n2), and determine the graphs that ...
