  • 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 ...
  • Mahbub, Md. Aman (University of Rajshahi, 2020-12)
    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 ...
  • Islam, Md. Anowarul (University of Rajshahi, 2001)
    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 ...
  • 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 ...
  • Rahman, Md. Lutfor (198)
    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 ...
  • Ali, Md. Ayub (University of Rajshahi, 1998)
    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 ...
  • 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 ...
  • Rahman, Md. Azizur (University of Rajshahi, 2011)
    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 ...
  • Latif, Md. Abdul (University of Rajshahi, 1994)
    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 ...
  • 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 ...
  • Rashid, Md. Mahbubur (University of Rajshahi, 2006)
    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. ...
  • Mollah, Md. Shirazul Hoque (University of Rajshahi, 2011)
    Suppose we seek a solution of the nonlinear system f(x={f;(x1,x2, ..., Xn)} = 0 i = 1,2, ..., n where f1, f2, f3, ...
  • 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 ...
  • Uddin, Md. Alhaz (University of Rajshahi, 2010)
    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 ...
  • Dey, Pinakee (University of Rajshahi, 2008)
    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 ...
  • Rahman, Md. Majedur (University of Rajshahi, 2003)
    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 ...
