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 Two Laplacian Matrices for Skew Gain Graphs
Roshni T Roy, Shahul Hameed K, Germina K A
Let be a graph with some prescribed orientation for the edges and be an arbitrary group. If be an anti-involution then the ske…

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…
