Signed Distance Laplacian Matrices for Signed Graphs
Roshni T Roy, K A Germina, K Shahul Hameed +1
A signed graph is a graph whose edges are labeled either positive or negative. Corresponding to the two signed distance matrices defined for signed graphs, we define two signed dis…
On the Characteristic Polynomial of Skew Gain Graphs
K. Shahul Hameed, Roshni T Roy, P. Soorya +1
Gain graphs are graphs where the edges are given some orientation and labeled with the elements (called gains) from a group so that gains are inverted when we reverse the direction…
On Signed Distance in Product of Signed Graphs
T. V. Shijin, P. Soorya, K. Shahul Hameed +1
A signed graph is a graph in which each edge has a positive or negative sign. In this article, first we characterize the distance compatibility in the case of a connected signed gr…
A Study on Set-Valuations of Signed Graphs
P. K. Ashraf, K. A. Germina, N. K. Sudev
Let be a non-empty ground set and be its power set. A set-labeling (or a set-valuation) of a graph is an injective set-valued function $f:V(G)\to \mathcal{…
On Products and Line Graphs of Signed Graphs, their Eigenvalues and Energy
K. A. Germina, Shahul Hameed K, Thomas Zaslavsky
In this article we examine the adjacency and Laplacian matrices and their eigenvalues and energies of the general product (non-complete extended -sum, or NEPS) of signed graphs.…
