    Existence and continuous dependence of mild solutions for impulsive fractional integrodifferential equations in Banach spaces

    In the present paper, we investigate the existence, uniqueness, and continuous dependence of mild solutions of impulsive neutral integrodifferential equations with nonlocal conditions in Banach spaces. We use ...

    A unified theory of contra-(μ,λ)-continuous functions in generalized topological spaces

    We introduce a new notion called contra-(μ,λ)-continuous functions as functions on generalized topological spaces [8]. We obtain some characterizations and several properties of such functions. The functions enab...

    A unified theory of generalized closed sets in weak structures

    A new kind of sets called generalized w-closed (briefly gw-closed) sets is introduced and studied in a topological space by using the concept of weak structures introduced by Á. Császár in [6]. The class of all g...
