Structural Characterizations and Algebraic Realizations of a Family of Regular Integral Graphs
Tapa Manna, Supriyo Dutta, Baby Bhattacharya
All the eigenvalues of an integral graphs are integers. Integral graphs are extremely rare. They form an asymptotically vanishing fraction among all graphs on verti…
Structural and Spectral Properties of Prime Order Element Graph of Finite Abelian Groups
Tapa Manna, Supriyo Dutta, Baby Bhattacharya
Given a finite group , the \emph{Prime Order Element (POE) Graph} consists of the group elements as the vertices, and two vertices and are adjacent if and only if…
Prime Order Element Graph of a Group -- II
Tapa Manna, Sauvik Poddar, Angsuman Das +1
In this sequel paper, we continue the analysis of the prime order element graph of a finite group , where vertices are elements of and edges connect distinct elements…
Forbidden Subgraphs of Prime Order Element Graph
Tapa Manna, Angsuman Das, Baby Bhattacharya
In this paper, we study different forbidden subgraph characterizations of the prime-order element graph defined on a finite group . Its set of vertices is the group a…
