On g-Extra Connectivity of Corona-Type Graph Products
Arati Sharma, Satyam Guragain, Ravi Srivastava
Connectivity is one of the central ideas in graph theory, especially when it comes to building fault-tolerant networks. A cutset of is defined to be the set of vertices in…
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…
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…
A graph product and its Application
Bishal Sonar, Ravi Srivastava
The spectrum of Laplacian and signless Laplacian matrix for a graph product is obtained, where both underlying graphs are regular. As an application of this, we have been able to g…
-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…
On the spectrum of closed neighborhood corona product of graph and its application
Bishal Sonar, Ravi Srivastava
In this paper, we investigate the spectral properties of the closed neighborhood corona product of graphs, which was introduced by Harishchandra S. Ramane et al.~\cite{ramane2021po…
A signed graph product and its Application
Bishal Sonar, Ravi Srivastava
A signed graph product is defined for a new product, and initially the unsigned graph product's Laplacian spectrum and signless Laplacian spectrum are found. Next, for the signed g…
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…
On spectrum of corona product of duplication signed graph and its application
Bishal Sonar, Ravi Srivastava
This paper introduces the concept of -signed and duplication signed graphs and shows that both are always structurally balanced. Using the duplication signed graph, we define th…
On Spectrum of Neighbourhood Corona Product of Signed Graphs
Bishal Sonar, Satyam Guragain, Ravi Srivastava
Given two signed graphs with nodes and , the neighbourhood corona, is the signed graph obtained by taking one copy of and …
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…
Structural balance and spectral properties of generalized corona product of signed graphs
Amrik Singh, Ravi Srivastava, Bibhas Adhikari +1
In this paper, we extend our earlier proposal of corona product of signed graphs into generalized corona product of signed graphs inspired by the generalized corona product of unsi…
