On Difference of Enhanced Power Graph and Power Graph of a Finite Group
Sucharita Biswas, Peter J. Cameron, Angsuman Das +1
The difference graph of a finite group is the difference of enhanced power graph of and power graph of , with all isolated vertices are removed. In this paper we…
On Perfectness of Annihilating-Ideal Graph of
Manideepa Saha, Sucharita Biswas, Angsuman Das
The annihilating-ideal graph of a commutative ring with unity is defined as the graph with the vertex set is the set of all non-zero ideals with non-zero annih…
On Co-Maximal Subgroup Graph of a Group
Angsuman Das, Manideepa Saha, Saba Al-Kaseasbeh
The co-maximal subgroup graph of a group is a graph whose vertices are non-trivial proper subgroups of and two vertices and are adjacent if . In this p…
Determining Number of Kneser Graphs: Exact Values and Improved Bounds
Angsuman Das, Hiranya Kishore Dey
The determining number of a graph is the minimum cardinality of a set such that pointwise stabilizer of under the action of is trivial. In t…
A Family of Tetravalent Half-transitive Graphs
Sucharita Biswas, Angsuman Das
In this paper, we introduce a new family of graphs, . We show that it is an infinite family of tetravalent half-transitive Cayley graphs. Apart from that, we determine some…
Classification of Cayley Rose Window Graphs
Angsuman Das, Arnab Mandal
Rose window graphs are a family of tetravalent graphs, introduced by Steve Wilson. Following it, Kovacs, Kutnar and Marusic classified the edge-transitive rose window graphs and Do…
Triameter of Graphs
Angsuman Das
In this paper, we introduce and study a new distance parameter {\it triameter} of a connected graph , which is defined as and is denot…
Partial Domination in Graphs
Angsuman Das
Let be a graph. For some with , a subset of is said to be a -partial dominating set if . The size of a smallest such is cal…
Subspace Sum Graph of a Vector Space
Angsuman Das
In this paper we introduce a graph structure, called subspace sum graph on a finite dimensional vector space where the vertex set is the coll…
On Perfectness of Intersection Graph of Ideals of
Angsuman Das
In this paper, we characterize the positive integers for which intersection graph of ideals of is perfect.
On Non-Zero Component Graph of Vector Spaces over Finite Fields
Angsuman Das
In this paper, we study non-zero component graph on a finite dimensional vector space over a finite field . We show that the graph is Hamil…
Non-Zero Component Graph of a Finite Dimensional Vector Space
Angsuman Das
In this paper, we introduce a graph structure, called non-zero component graph on finite dimensional vector spaces. We show that the graph is connected and find its domination numb…
An efficient multi-use multi-secret sharing scheme based on hash function
Angsuman Das, Avishek Adhikari
In this paper, a renewable, multi-use, multi-secret sharing scheme for general access structure based on one-way collision resistant hash function is presented in which each partic…
