We study quantum mechanical aspect of black holes. We give a brief re view of black hole radiation which is commonly called Hawking radiation. So far several different methods have been employed to investigate this radiation ...
The main contents of this thesis may be briefly summarized
as follows:
Chapter 1 contains a brief account of the Plebonski spacetime . We specify there the various spacial class of spacetimes covered by the Plebanski ...

This thesis studies the nature of a sectionally pseudocomplemented distributive nearlattice. By a nearlattice S we will always mean a meet semilattice together with the property th9.t any two elements possessing a common ...
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 ...
In 1965, Zadeh[150] introduced to the world the term fuzzy set(FS), as a formalization of vagueness and partial truth, and represents a degree of membership for each member of the universe of discourse to a subset of it. ...
Azad, Md. Abul Kalam(University of Rajshahi, 2004)
The theory of turbulent motion has received considerable attention in recent developments of high-speed jet aircraft, plasma physics and chemical engineering. The formation of a turbulent boundary layer is one of the most ...
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 ...
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 ...
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 ...
In this thesis hydromagnetic stabilities with respect to both axisymmetric and nonaxisymmetric perturbations of an incompressible perfectly conducting viscous fluid in presence of a magnetic field has been investigated. ...
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 ...

Classification is a deep and fundamental problem in every branch of Mathematics. Although an uphill task, this target has been achieved in a number of cases in different fields. In general, the strategy for this grand ...
In many branches of Mathematics, a strategy for study of the mathematical entities is to view them as being made up of simpler entities in one or more ways. The task is then divided into two parts: (i) identifying and ...
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 ...
This thesis studies the nature of distributive nearlattices. By a nearlattice S we will always mean a (lower) semilattice which· has the property that any two elements possessing a common upper bound,have a supremum, Cornish ...
Khaton, Mst. Zamilla(University of Rajshahi, Rajshahi, 2021)
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 ...
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 ...
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 ...
After a short review of spacetime singularities, blackholes, we introduce one with the laws of blackhole mechanics and the laws of ordinary thermodynamics. We discuss the remarkable analogy between the laws of blackhole ...
