On the spectral radius and energy of signless Laplacian matrix of digraphs [PDF]
Heliyon, 2022 Let D be a digraph of order n and with a arcs. The signless Laplacian matrix Q(D) of D is defined as Q(D)=Deg(D)+A(D), where A(D) is the adjacency matrix and Deg(D) is the diagonal matrix of vertex out-degrees of D.

On Distance Signless Laplacian Spectral Radius and Distance Signless Laplacian Energy [PDF]
Mathematics, 2020 In this article, we find sharp lower bounds for the spectral radius of the distance signless Laplacian matrix of a simple undirected connected graph and we apply these results to obtain sharp upper bounds for the distance signless Laplacian energy graph.

Color signless Laplacian energy of graphs [PDF]
AKCE International Journal of Graphs and Combinatorics, 2017 In this paper, we introduce the new concept of color Signless Laplacian energy . It depends on the underlying graph and the colors of the vertices. Moreover, we compute color signless Laplacian spectrum and the color signless Laplacian energy of families

On distance signless Laplacian spectrum and energy of graphs [PDF]
Electronic Journal of Graph Theory and Applications, 2018 The distance signless Laplacian spectral radius of a connected graph G is the largest eigenvalue of the distance signless Laplacian matrix of G, defined as DQ(G) = Tr(G) + D(G), where D(G) is the distance matrix of G and Tr(G) is the diagonal ...

Intuitionistic fuzzy approach based on correlation coefficient and signless Laplacian energy with applications [PDF]
Scientific ReportsDecision-making in uncertain and complex environments requires methods that can effectively capture ambiguity in expert judgments. Traditional fuzzy graph models often overlook non-membership and hesitation degrees, limiting their descriptive power.
