The focus of this paper is to establish a new concept b-hybrid fuzzy contraction regarding the study fixed-point theorems in setting b-metric spaces. This idea harmonizes and refines several well-known results direction point-valued, multivalued, fuzzy-set-valued maps comparable literature. To attract researchers field, some important are shown be corollaries. Moreover, result presented suffici...

Many questions concerning the semantics of disjunctive databases and of logic programming systems depend on the fixed points of various multivalued mappings and operators determined by the database or program. We discuss known versions, for multivalued mappings, of the Knaster-Tarski theorem and of the Banach contraction mapping theorem, and formulate a version of the classical fixed-point theo...

In this paper we consider continuity of the set of fixed points and approximate fixed points for parameterized set-valued mappings. Continuity properties are provided for the fixed points of general multivalued mappings, with additional results shown for contraction mappings. Further analysis is provided for the continuity of the approximate fixed points of set-valued functions. Additional resu...

In this paper, we numerically study the semiclassical limit of the SchrödingerPoisson equations as a selection principle for the weak solution of the VlasovPoisson in one space dimension. Our numerical results show that this limit gives the weak solution that agrees with the zero diffusion limit of the Fokker-Planck equation. We also numerically justify the multivalued solution given by a momen...
