Bounds on Elliptic Sombor and Euler Sombor indices of join and corona product of graphs
Bishal Sonar, Ravi Srivastava
The Elliptic Somber and Euler Somber indices are newly defined topological indices based on the Somber index. Our paper presents calculations of the upper and lower bounds of these…
-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…
