Welcome to the Institutional Repository of Vidyasagar University
Dspace@VU is the Open Access Institutional Repository of Vidyasagar University. Research outputs of VU - journal papers, conference papers, reports, theses, patents etc. - are uploaded/self-archived by VU Faculty members / Resarchers who do research on different specialized areas . Interested users can freely download and use documents as most of them are directly accessible and full-text downloadable. 'Request Copy' forms can be used for documents to which direct full-text download is restricted due to publisher embargo. "This repository is administrated by Central Library , Vidyasagar University".
Digitized administrative documents ,Articles of the journals published by the university and old question papers of Vidyasagar University as and when made available have been uploaded in this repository
Repository is indexed by Google, Google Scholar, OAIster, ROAR, OpenDOAR, BASE
"Academic departments are requested to submit to the University Library the list of on-going PhD theses and other research projects taken up by the respective departments with relevant details for uploading in this repository.

The Novel Concept of Roman Domination in Fuzzy Graph
See
Suppose = , is a graph. A Roman dominating function (RDF) of is a function
: → {0,1,2} such that every vertex for which = 0 has a neighbor with =
2. The weight of an RDF is = Σ ∈ . The Roman domination number
(RDN) of a graph , denoted by ℘ , is the minimum weight of all possible RDFs. In
this study, we define RDF on fuzzy graph (FG). Our purpose is to develop a notion of the
RDF and also to present some basic definitions, notations, remarks, and p...
On the Exponential Diophantine Equation 27^x – 11^y = z^2
See
In this article, we study and establish the theorem of the exponential Diophantine equation
27^x -11^y = z^2 , which has exactly two solutions where x, y and z are non-negative
integers using Catalan’s conjecture, modular arithmetic, factorial method and elementary
mathematical concepts.
Almost Pseudo-Ricci Symmetric Mixed Generalized Quasi-Einstein Space-time
See
In this paper, an almost pseudo-Ricci symmetric mixed generalized quasi-Einstein spacetime
has been revealed where the nature of associated vector fields is observed.
A Survey on Interval-valued Fuzzy Graphs
See
Interval-valued fuzzy graphs (IVFGs) belonging to the fuzzy graphs (FGs) family, have
good capabilities when faced with problems that cannot be expressed by FGs. The notion
of an IVFG is a new mathematical attitude to model the ambiguity and uncertainty in
decision-making issues. IVFGs are well-articulated, useful and practical tools to manage
the uncertainty preoccupied in all real-life difficulties where not sure facts, figures and
explorations are explained. In this paper, the concept...
Certain Types of Vertices in m-Polar Fuzzy Graphs
See
In this study, we explore the concept of m-polar fuzzy (mPF) detour g-eccentric nodes
within m-polar fuzzy graphs (mPFGs). We delve into the idea of mPF detour g-interior
nodes and mPF detour g-boundary nodes, examining their significance and properties.
Additionally, we establish the relationship between mPF detour g-boundary vertices and
mPF cut vertices.
A Study of Thermodynamic Heat Transfer and System Efficiency
See
In this paper, we try to provide an overview of thermodynamics first and second laws,
which mainly deal with the transfer of heat. We mainly focus on heat transfer devices and
the efficiency of energy conversion. We discuss and construct different cycles, taking into
consideration the conversion of any forms of energy under consideration, in particular heat,
to work on a continuous basis, which is the fundamental objective of nuclear power plant
owners. One needs to have a better underst...
General Solution of the Diophantine Equation M^x p + (M q + 1)^y= (lz)^2
See
In this article, I study and solve the exponential Diophantine equation M^x p + (M q + 1)^y= (lz)^2 where M p and M q are Mersenne primes, l is a prime number, and x, y and z are non-negative integers. Several illustrations are presented as well as cases where no solution of the given Diophantine equation is present.
