  • 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 ...
  • Study On Some Problems of Non-Newtonian Fluid Mechanics 
    Hossain, Md. Aslam (University of Rajshahi, 2010)
    This is an elaborate discussion of main theme ideas and the condition in "Fluid mechanics", which help us to realized a clear concept of the background and elements of various viscous Newtonian and non-Newtonian flow ...
  • Eulerian Method for Third Order Linear Systems 
    Haque, Md. Abdul (University of Rajshahi, 2003)
    In this thesis, we have studied the solutions of the various types of third order linear systems of ordinary differential equations. In chapter I, we have considered the third order linear homogeneous system with constant ...
  • Legume Crops and Nitrogen Fixing Bacteria in Barind Tract

    Legume Crops and Nitrogen Fixing Bacteria in Barind Tract Studies were undertaken to isolate, screen and characterize rhizobial bacteria from 12 different pulse legumes grown at different locations of Barind tract. Thirty-one ...
  • On Principal n-ideals of a Distributive nearlattice 
    Raihan, Md. Sazuwar (University of Rajshahi, 2006)
    This thesis studies some of the nature of Principal n-ideal of a distributive near lattice. The n-ideals of a lattice have been studied by several authors including [4] and [36]. For a fixed element n of a lattice L, a ...
  • KBM Asymptotic Method for third order Nonlinear Oscillations 
    Alam, Md. Shamsul (University of Rajshahi, 2000)
    In most treatments or nonlinear oscillations hy perturbation method. only periodic oscillations are treated; transients are not considered. Krylov and Bogoliubov have used a perturbation method to discuss transients in the ...
  • On Finitely Generated n-ldeals of a Nearlattice 
    Rahman, Md. Mizanur (University of Rajshahi, 2006)
    The thesis studies extensively the nature of finitely generated n-ideals of a near lattice. Many authors including [1], [34] and [35] have studied about n-ideals of a lattice. A convex sublattice containing a fixed element ...
  • On Some Universal Constructions for Fuzzy Topological Spaces 
    Rashid, Mohammed Harunor (University of Rajshahi, 2005)
    In this work, many known universal objects such as products, equalizers, pullbacks and their duals, namely, coproducts, coequalizers and pushouts for fuzzy topological spaces are studied in detail. Another known concept ...
  • Cosmic String in theory of General Relativity 
    Biswas, Md.Elias Uddin (1997)
    This thesis is organized as follows. Chapter I contains a brief discussion of the production of various topological defects in cosmological phase transitions in the early universe. The three kinds of topological defects ...
  • Asymptotic Methods for some third order Nonlinear Differential Equations 
    Alam, Md. Shamsul (University of Rajshahi, 1995)
    In this thesis, we investigate the oscillations of third order nonlinear systems by the asymptotic method. The asymptotic method of Krylov-Bogoliubov-Mitropolskii (KBM) is a popular technigue for obtaining analytic solution ...
  • Investigation of Some Aspects of Protoplanetary Model of Planetary Formation 
    Paul, Gour Chandra (University of Rajshahi, 2005)
    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 ...
  • A Study on Distributive Nearlattices 
    Rahman, Md.Bazlar (University of Rajshahi, 1994)
    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 ...
