  • 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. ...
  • 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. ...
  • On Fuzzy Compactness 
    Talukder, Md. Abdul Mottalib (University of Rajshahi, 2015)
    The fundamental concept of a fuzzy set and fuzzy set operations was first introduced by L. A. Zadeh [175] in 1965 and it provides a natural foundation for treating mathematically the fuzzy phenomena, which exists pervasively ...
  • New Approximate Solution of Non-Linear Differential Systems 
    Pervin, Mst. Razia (University of Rajshahi, 2014)
    Most of the perturbation methods are developed to find periodic solutions of nonlinear systems; transients are not considered. At first, Krylov and Bogoliubov introduced a perturbation method which is well known as “asymptotic ...
  • Analysis on Viscous Incompressible Thermal Flow on a Ventilated Enclosure by Finite Element Method 
    Ahammad, Main Uddin (University of Rajshahi, 2014)
    Heat transfer in enclosure in which the influence of free (natural) and forced convection (mixed convection) are of comparable magnitude occurs frequently in engineering situations. The applications include the heat ...
  • Characterizations of Prime and Semiprime Gamma Rings with Derivations and Lie Ideals 
    Rahman, Md. Mizanor (University of Rajshahi, 2014)
    Gamma ring was first introduced by N. Nobusawa as a generalization of a classical ring. W. E. Barnes generalized the definition of a gamma ring due to Nobusawa. Presently the gamma ring due to Barnes is known as a gamma ...
  • A Study on Fixed Point Iterative Procedures 
    Khatun, Miss. Saleha (University of Rajshahi, 2016)
    Fixed point theory has fascinated hundreds of researchers since 1922 with the celebrated Banach’s fixed point theorem. Fixed point iterative procedures are one of the early achievements of fixed point theory for their ...
