Automorphism group of the reduced power (di)graph of a finite group
T. Anitha, R. Rajkumar
We describe the full automorphism group of the directed reduced power graph and the undirected reduced power graph of a finite group. We compute the full automorphism groups of the…
Exponential Stability of Nonlinear Fractional Stochastic System with Poisson Jumps
P. Balasubramaniam, T. Sathiyaraj, K. Priya
In this paper exponential stability of nonlinear fractional order stochastic system with Poisson jumps is studied in finite dimensional space. Existence and uniqueness of solution,…
Spectra of generalized corona of graphs constrained by vertex subsets
R. Rajkumar, M. Gayathri
In this paper, we introduce a generalization of corona of graphs. This construction generalizes the generalized corona of graphs (consequently, the corona of graphs), the cluster o…
An Integrated Method of Data Hiding and Compression of Medical Images
M. MaryShanthi Rani, S. Lakshmanan
A new technique for embedding data into an image coupled with compression has been proposed in this paper. A fast and efficient coding algorithms are needed for effective storage a…
Coprime graph of subgroups of a group
R. Rajkumar, P. Devi
Let be a group. We define the coprime graph of subgroups of , denoted by , is a graph whose vertex set is the set of all proper subgroups of , and two dist…
Intersection graph of cyclic subgroups of groups
R. Rajkumar, P. Devi
Let be a group. The intersection graph of cyclic subgroups of , denoted by , is a graph having all the proper cyclic subgroups of as its vertices and tw…
Classification of finite groups with toroidal or projective-planar permutability graphs
R. Rajkumar, P. Devi, Andrei Gagarin
Let be a group. The permutability graph of subgroups of , denoted by , is a graph having all the proper subgroups of as its vertices, and two subgroups are adjacen…
Permutability graphs of subgroups of some finite non-abelian groups
R. Rajkumar, P. Devi
In this paper, we study the structure of the permutability graphs of subgroups, and the permutability graphs of non-normal subgroups of the following groups: the dihedral groups $D…
