Laplacian Spectrum of cozero-divisor graphs of commutative polynomial rings
Sarbari Mitra, Soumya Bhoumik
The cozero-divisor graph of a commutative ring , denoted , is the graph whose vertices are the non-zero and non-unit elements of , with two distinct vertices and $…
On Perrin Cordial Labeling: A New Approach in Graph Labeling Theory
Sarbari Mitra, Soumya Bhoumik
In this paper, we introduce the concept of \emph{Perrin cordial labeling}, a novel vertex labeling scheme inspired by the Perrin number sequence and situated within the broader fra…
On Laplacian and Signless Laplacian Permanental Polynomials of Some Well-known Graphs
Sarbari Mitra, Soumya Bhoumik
The permanent of an matrix is defined as , where denotes the symmetric group on $\{1,2…
A Study of Fibonacci Cordial Labeling in Structured Graph Families
Sarbari Mitra, Soumya Bhoumik
A \emph{Fibonacci cordial labeling} of a graph \( G \) is an injective function \( f: V(G) \rightarrow \{F_0, F_1, \dots, F_n\} \), where \( F_i \) denotes the \( i^{\text{th}} \)…
