The thesis is concerned with generalizations of some important and
interesting properties of separation, compactness and connectedness in a
span of seven chapters.
In the first chapter pseudo regular and pseudo normal ...

In this work, we deal with the two types of variational inclusions. Firstly, we consider
the variational inclusion problem of the form
0 ∈ ζ(¯s) + g(¯s) + ξ(¯s), (A)
where S and T are Banach spaces, ζ : S → T is ...
The fundamental concept of a fuzzy set and fuzzy set operations was first introduced
by L. A. Zadeh (Zadeh, 1965) in 1965 and it provides a natural foundation for treating
mathematically the fuzzy phenomena, which exists ...
The thesis entitled "Theoretical investigations of turbulence and Magnetohydrodynamic
turbulence in incompressible fluid" is being presented for the
award of the degree of Doctor of Philosophy in Mathematics. It is the ...
We investigate the motion of spinning particles, such as Dirac fermions, in curved spacetimes by pseudo-classical mechanics models in which the spin degrees of freedom are characterized in terms of anti-commuting Grassmann ...
The thesis entitled "Analytical Investigations in Turbulent and MHD Turbulent Flow" is being presented for the award of the degree of Doctor of Philosophy in Mathematics. It is the outcome of my research conducted in the ...
This thesis studies extensively the finitely generated n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor in studying the kernels around a particular element n, of a skeletal ...
In Introduction we give a brief account of our work of studying spinning particles in curved spacetime of General Relativity.
In Chapter I we discuss the relevant equations for the motion of spinning particles in curved ...
The development of real time operational surge prediction system in the Bay of Bengal incorporating air bubble effects is still limited and is needed immediate attention. In this respects the study has been focused the ...
This thesis studies the nature of n-ideals of a lattice. The topic arose out of a study on the kernels, around a particular element n, of a skeletal congruence on a distributive lattice. The idea of n-ideals in a lattice ...
In this thesis we have investigated some aspects of the protoplanetary theory of planetary formation, namely, the structure of a protoplanet, sedimentation of heavy elements in a protoplanet, and the effect of mass loss ...

The present thesis entitled "Characterizations of Some Radical Rings and Gamma Rings" is the outcome of the research by me under the supervision of Dr. A. C. Paul, Professor, Department of Mathematics, University of Rajshahi. ...
The various topological concepts and properties like openness, closedness, continuity, compactness, connectedness etc. have been generalised by mathematicians. In this thesis we have studied these generalisations and made ...
Most of the perturbation methods are developed to find the periodic solutions of nonlinear systems with small nonlinearities, transients are not considered. In 1947, first Russian scientists Krylov and Bogo Liubov introduced ...
Begum, Shamsun Naher(University of Rajshahi, 2010)
This thesis Centre’s on a class of certain pseudo complemented partial lattices. This partial lattice is said to be a JP-semilattice. An algebraic structure S = (S, /\, V), where (S, /\) is a semilattice and V is a partial ...
Pramanik, Jogendra Nath(University of Rajshahi, 2005)
In this thesis we have investigated some aspects of stellar structure and evolution. The thesis is divided into two sections. Section I deals with the structure of a star while section 2 deals with stu.J.y .. of some young ...
There are many approaches for approximating solutions of nonlinear vibrating problems. The most common methods for constructing approximate analytical solutions to the nonlinear vibrating problems are the perturbation ...
In order to find the approximate numerical solution to a system of nonlinear equations as well as an integral and a differential operator equations, Newton's algorithm is widely used. L. V. Kantorovich [1948] and Moore ...
