  1. Hydromagnetic natural convection flow with heat and mass transfer of a chemically reacting and heat absorbing fluid past an accelerated moving vertical plate with ramped temperature and ramped surface concentration through a porous medium

    Journal of the Egyptian Mathematical Society 23(1):197 (2015)

    Unsteady hydromagnetic natural convection flow with heat and mass transfer of an electrically conducting, viscous, incompressible, chemically reacting and heat absorbing fluid past an accelerated moving vertical plate with ramped temperature and ramped surface concentration through a p...

  3. On asymptotically ideal equivalent sequences

    Journal of the Egyptian Mathematical Society 23(1):67 (2015)

    In this article we introduce the notion of asymptotically I-equivalent sequences. We prove the decomposition theorem for asymptotically I-equivalent sequences. Further, we will present four theorems that characterize asymptotically I-equivalent of multiple λ and the regularity of asymp...
  4. Convergence to non-autonomous differential equations of second order

    Journal of the Egyptian Mathematical Society 23(1):27 (2015)

    In this paper, we consider a non-autonomous differential equation of second orderx″+m(t)f(x′)+n(t)g(x)=p(t,x,x′). By the Lyapunov function approach, we discuss the convergence of solutions of the equation considered. Our findings generalize some earlier results in the literat...
  5. Existence, uniqueness and stability of random impulsive neutral partial differential equations

    Journal of the Egyptian Mathematical Society 23(1):31 (2015)

    In this paper, the existence, uniqueness and stability via continuous dependence of mild solution of neutral partial differential equations with random impulses are studied under sufficient condition via fixed point theory.
  6. Higher-order duality for multiobjective programming problem involving [formula omitted]-invex functions

    Journal of the Egyptian Mathematical Society 23(1):12 (2015)

    In the present article, we formulate two different kinds of higher-order dual models related to the multi-objective programming problem containing arbitrary norms. Furthermore, weak, strong and strict converse duality results are established under the assumptions of higher-order (Φ,ρ)-...
  7. On the families of q-Euler polynomials and their applications

    Journal of the Egyptian Mathematical Society 23(1):1 (2015)

    In this paper, we focus on applications of q-Euler polynomials and obtain some new combinatorial relations by using p-adic q-integral on Zp. Moreover, we derive distribution formula (Multiplication Theorem) for Dirichlet type of q-Euler numbers and polynomials with weight α. Also we ap...
  8. A dynamic Cournot duopoly model with different strategies

    Journal of the Egyptian Mathematical Society 23(1):56 (2015)

    This paper analyzes the dynamics of a Cournot duopoly model with different strategies. We offer results on existence, stability and local bifurcations of the equilibrium points. The bifurcation diagrams and Lyapunov exponents of the model are presented to show that the model behaves ch...
  9. Exact solutions of nonlinear wave equations using (G′/G, 1/G)-expansion method

    Journal of the Egyptian Mathematical Society 23(1):78 (2015)

    In this paper, the (G′/G,1/G)-expansion method with the aid of Maple is used to obtain new exact travelling wave solutions of the Hamiltonian amplitude equation and the Broer–Kaup equations arise in the analysis of various problems in fluid mechanics, theoretical physics. The travellin...
  10. Fuzzy cyclic contraction and fixed point theorems

    Journal of the Egyptian Mathematical Society 23(1):139 (2015)

    In this paper, we consider some fuzzy cyclic contractions and prove the existence and uniqueness of fixed points of operators belong to a class consisting fuzzy cyclic operators defined on a subset of a fuzzy metric space. We also furnish some illustrative examples to support our main ...
