    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. …”

    Analysis of Sustainable Development in Local Spaces: The Application of the Theory of Fuzzy Sets by Maria Luisa García Batiz, Lucio Flores Payan, Betriz Adriana Venegas Sahagún

    Published 2016-01-01
    “…In order to undertake this study, an Index of Sustainable Local Development (IDSL) was created drawing on the theory of fuzzy logic. This index permits us to analyze and compare sustainable development in three dimensions of the environmental system at the local level: social, environmental and economic. …”
