The Spectral Theory of Threshold Graphs: A Survey

Pallabi Manna, Santanu Mandal, Fernando C. Tura

Threshold graphs-the -free graphs, equivalently those built from a single vertex by repeatedly adding isolated or dominating vertices-are among the most thoroug…

The Distance Laplacian and Distance Signless Laplacian Spectra of -Graphs

Santanu Mandal, Pallabi Manna

Mandal and Mehatari (\emph{Comp.\ Appl.\ Math.}, 2025) introduced the class of cographs generated by a finite creation sequence of natural numbers,…

On finite groups whose power graph is claw-free

Pallabi Manna, Santanu Mandal, Andrea Lucchini

A graph is called claw-free if it contains no induced subgraph isomorphic to the complete bipartite graph . The undirected power graph of a group has vertices the ele…

Co-maximal subgroup graph characterized by forbidden subgraphs

Pallabi Manna, Santanu Mandal, Manideepa Saha

In this communication, the co-maximal subgroup graph of a finite group is examined when is a finite nilpotent group, finite abelian group, dihedral group , dicy…

Further study on forbidden subgraphs of power graph

Santanu Mandal, Pallabi Manna

The undirected power graph (or simply power graph) of a group , denoted by , is a graph whose vertices are the elements of the group , in which two vertices and …

Intersection subgroup graph with forbidden subgraphs

Santanu Mandal, Pallabi Manna

Let be a group. The intersection subgroup graph of (introduced by Anderson et al. \cite{anderson}) is the simple graph whose vertices are those non-trivial subgr…

On chordality of the power graph of finite groups

Pallabi Manna, Ranjit Mehatari

A graph is called chordal if it forbids induced cycles of length 4 or more. In this paper, we attempt to identify the non-nilpotent groups whose power graph is a chordal graph (thi…

On finite groups whose power graph is a cograph

Peter J. Cameron, Pallabi Manna, Ranjit Mehatari

A -free graph is called a cograph. In this paper we partially characterize finite groups whose power graph is a cograph. As we will see, this problem is a generalization of th…
