Characterizing finite groups whose order supergraphs satisfy a connectivity condition

Ramesh Prasad Panda, Papi Ray

Let $I^$ be an undirected and simple graph. A set $S$ of vertices in $I^$ is called a {cyclic vertex cutset} of $I^$ if $I^ - S$ is disconnected and has at least two components ea…

Forbidden subgraphs on conjugacy class graphs of groups

Papi Ray, Sonakshee Arora, Xuanlong Ma

Let $G$ be a finite group. The commuting (resp. nilpotent) conjugacy class graph $I^_{C C C} (G)$ (resp. $I^_{N C C} (G)$ ) of $G$ is a simple graph whose vertex set consists of all non-c…

A Relationship Between Character Values Of Wreath Products And The Symmetric Group

Rijubrata Kundu, Papi Ray

A relation between certain irreducible character values of the hyperoctahedral group $B_{n}$ ( $Z /2 Z ≀ S_{n}$ ) and the symmetric group $S_{2 n}$ was proved by F. LÃ¼b…
