    The Study of Fixed Point Theory for Various Multivalued Non-Self-Maps by Wei-Shih Du, Erdal Karapınar, Naseer Shahzad

    Published 2013-01-01
    “…The basic motivation of this paper is to extend, generalize, and improve several fundamental results on the existence (and uniqueness) of coincidence points and fixed points for well-known maps in the literature such as Kannan type, Chatterjea type, Mizoguchi-Takahashi type, Berinde-Berinde type, Du type, and other types from the class of self-maps to the class of non-self-maps in the framework of the metric fixed point theory. We establish some fixed/coincidence point theorems for multivalued non-self-maps in the context of complete metric spaces.…”

    Stable Dyonic Thin-Shell Wormholes in Low-Energy String Theory by Ali Övgün, Kimet Jusufi

    Published 2017-01-01
    “…In this paper, we construct a four-dimensional, spherically symmetric, dyonic thin-shell wormhole with electric charge Q, magnetic charge P, and dilaton charge Σ, in the context of Einstein-Maxwell-dilaton theory. We have applied Darmois-Israel formalism and the cut-and-paste method by joining together two identical space-time solutions. …”

    Spherically Symmetric Solution in (1+4)-Dimensional f(T) Gravity Theories by Gamal G. L. Nashed

    Published 2014-01-01
    “…A nondiagonal spherically symmetric tetrad field, involving four unknown functions of radial coordinate r plus an angle Φ, which is a generalization of the azimuthal angle ϕ, is applied to the field equations of (1+4)-dimensional f(T) gravity theory. A special vacuum solution with one constant of integration is derived. …”
