  • Quantum Effects of Black Holes 
    SULTANA, KAUSARI (University of Rajshahi, 2014)
    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 ...
  • Quantum Gravity in Curved Space-Time of General Relativity

    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 ...
  • Sectionally Pseudocomplemented Distributive Nearlattices 
    Islam, A. K. M. Sirajul (University of Rajshahi, 1998)
    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 ...
  • Semilattices with a Partial Binary Operation 
    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 ...
  • Separation Axioms in Intuitionistic Fuzzy Topological Spaces 
    Ahmed, Estiaq (University of Rajshahi, 2015)
    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. ...
  • Separation Axioms on L-Topological Spaces 
    Islam, Rafiqul (University of Rajshahi, 2015)
    The notion of a fuzzy set, as proposed by L.A. Zadeh[90] in 1965 to provide a foundation for the evolution of many areas of knowledge. After then in quick succession, L-fuzzy sets were introduced by Goguen[24] in 1967. ...
  • Some Theoretical Studies on Turbulence and Magneto-Hydrodynamic Turbulence 
    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 ...
  • Some Topics in Fuzzy Topological Spaces 
    Hossain, Md. Sahadat (University of Rajshahi, 2004)
    The concept of fuzzy set was introduced by the American Mathematician L. A. Zadeh for the first time in 1965. This provides a natural framework for generalizing many algebraic and topological concepts in various directions. ...
  • Spinning Particles in Curved Spacetime of General Relativity 
    Ali, M. Hossain (University of Rajshahi, 2001)
    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 ...
  • Stability Analysis of Some Mathematical Models of Epidemics 
    Islam, Md. Saiful (University of Rajshahi, 2013)
    The spread of communicable diseases is often described mathematically by compartmental models. Many epidemiological models have a Disease Free Equilibrium (DFE) at which the population remains in the absence of disease. ...
  • Structure of an initial n1ain sequence star of 1nixed opacity with negligible abundance of heavy ele1nents and studies of so1ne young clusters 
    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 ...
  • Studies of Spinning Particles in Curved Spacetimes 
    Banu, Akhtara (University of Rajshahi, 2010)
    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 ...
  • Studies on Hydromagnetic Stability of Newtonian and Non-Newtonian Fluid 
    Rahman, M. Monsur (University of Rajshahi, 2004)
    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. ...
  • A Study of Characterization of Some Regular Gamma Rings 
    Nazneen, Ayesha (University of Rajshahi, 2003)
    The present thesis entitled, "A Study of Characterization of Some Regular Gamma Rings " is the outcome of researches carried out by me under the close supervision of Dr. Akhil Chandra Paul, Professor, Department of ...
  • Study of Radicals and Semisimple Classes of Rings 
    Dey, Kalyan Kumar (University of Rajshahi, 2002)
    The concept of the radical of a ring was introduced by Artin for rings with the descending chain condition with a view to obtaining a nice structure theorem for the ring. The idea was to single out the Toblerone part, of ...
  • Study of Some Properties of Topological Spaces and of Their Generalisations 
    Mitra, Mallika (University of Rajshahi, 2006)
    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 ...
  • Study of Structures in Some Branches of Mathematics 
    Hossain, Mohd. Altab (University of Rajshahi, 2006)
    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 ...
  • Study of Sums and Products in Some Branches of Mathematics 
    Dey, Kalyan Kumar (University of Rajshahi, 2006)
    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 ...
  • A Study on Convergence of Newton's Method in Real and Interval Number 
    Rahman, Md. Majedur (University of Rajshahi, 2003)
