  • 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 ...
  • Rahman, Zillur (University of Rajshahi, Rajshahi, 2021)
    Fractional derivatives are most important to accurate nonlinear modeling of various real-world difficulties in applied nonlinear science and engineering incidents especially in the fields of crystal, optics and quantum ...
  • Hossen, Md. Belal (University of Rajshahi, Rajshahi, 2020)
    Nonlinear evolution equations (NLEEs) play a noteworthy role in various scientific and engineering fields such as applied mathematics, plasma physics, fluid dynamics, optical fibers, biology, solid state physics, chemical ...
  • Ullah, Mohammad Safi (University of Rajshahi, Rajshahi, 2021)
    Most of the natural happenings can be present by nonlinear modeling. The soliton theory is a highly effective section of nonlinear sciences that includes soliton, multi-soliton, rational, breather line, breather kinky, ...
  • 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 ...
  • Asaduzzaman, Md. (University of Rajshahi, 2011)
    Fixed point theory has fascinated hundreds of researchers since 1922 with the celebrated Banach's fixed point theorem. There exists a vast literature on the topic and this is a very active field of research at present. Let ...
  • Hoque, Md. Fazlul (University of Rajshahi, 2011)
    The fundamental concept of a fuzzy set was introduced by L. A. Zadeh [111] in 1965 to provide a foundation for the development of many areas of knowledge. Consequently, this provides a natural frame work for generalizing ...
  • Malek, Abdul (University of Rajshahi, 2009)
    A theoretical study of oxygen diffusion process through living tissues and its various consequences have been presented. In this aspect we have reviewed some physiological terms and fundamental lows of diffusion. A ...
  • Azam, S. M. Faqruddin Ali (University of Rajshahi, 2011)
    The goal of this thesis is to find out some new R1 -concepts for fuzzy topological spaces. Besides some concepts of fuzzy R0, R1, T0, T1, T2 and regular topological spaces that are already existing in the literature are ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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 ...
  • 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. ...
  • Syeed, Ahmed, Abu Sadat (University of Rajshahi, 2014)
    This thesis studies the nature of standard n-ideals of a lattice. The idea of n-ideals in a lattice was first introduced by Cornish and Noor. For a fixed element n of a lattice L, a convex sublattice containing n is called ...
  • Shayid, Md.Abu (University of Rajshahi, 2013)
    The goal of the thesis is to find out some new connectedness concepts in fuzzy topological spaces. Some concepts of connectedness in fuzzy topological spaces that already exist in the literature are recalled here also. In ...
  • 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. ...
  • Sultana, Mst. Shamima (University of Rajshahi, 2003)
    The conception of turbulent flow and the accompanying transition from laminar to turbulent flow is of fundamental importance. In everyday life, we recognized three states of matter: solid, liquid and gas. Although different ...
  • Biswas, Sanjoy Kumar (University of Rajshahi, 2015)
    The thesis is concerned with generalizations of some important and interesting properties of topological and bitopological spaces in a span of four chapters. The first chapter constitutes an introduction and study of (i) ...
  • 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. ...
