On the strong geodeticity in the corona type product of graphs
Bishal Sonar, Satyam Guragain, Ravi Srivastava
The paper focuses on studying strong geodetic sets and numbers in the context of corona-type products of graphs. Our primary focus is on three variations of the corona products: th…
-edge geodetic graphs
Satyam Guragain, Ravi Srivastava
A graph is -edge geodetic graph if every edge of lies in at least one geodesic of length . We studied some basic properties of -edge geodetic graphs. We investigat…
r-orientation of a signed graph and its application on coronae of signed graphs
Satyam Guragain, Ravi Srivastava, Bishal Sonar
For unsigned graphs G and H, the characteristic polynomial of different graph matrices for edge corona, subdivision vertex neighbourhood corona and subdivision edge neighbourhood c…
Interlacing Properties of Eigenvalues of Laplacian and Net-Laplacian Matrix of Signed Graphs
Satyam Guragain, Ravi Srivastava
This paper explores interlacing inequalities in the Laplacian spectrum of signed cycles and investigates interlacing relationship between the spectrum of the net-Laplacian of a sig…
