Variants of the New Caristi Theorem

نویسندگان

چکیده

The well-known Caristi fixed point theorem has numerous generalizations and modifications. Recently there
 have appeared its equivalent dual forms based on new concept of lower semicontinuity
 from above by several authors. In the present article, we give proofs such versions their
 formulations applying our Metatheorem in ordered theory.

Functional Versions of the Caristi-kirk Theorem

Many functional versions of the Caristi-Kirk fixed point theorem are nothing but logical equivalents of the result in question.

Quasicone Metric Spaces and Generalizations of Caristi Kirk's Theorem

Cone-valued lower semicontinuous maps are used to generalize Cristi-Kirik’s fixed point theorem to Cone metric spaces. The cone under consideration is assumed to be strongly minihedral and normal. First we prove such a type of fixed point theorem in compact cone metric spaces and then generalize to complete cone metric spaces. Some more general results are also obtained in quasicone metric spaces.

Caristi Type Coincidence Point Theorem in Topological Spaces

The paper is concerned with a very general version of Caristi’s coincidence theorem, in topological spaces (X, τ) satisfying some completeness conditions with respect to a function p : X ×X → [0,∞), and having as consequence Caristi’s fixed point theorem. The general result is applied to various concrete situations quasi-metric spaces, bornological spaces to obtain versions of Ekeland’s variati...

new semigroup compactifications via the enveloping semigroups of associated flows

this thesis deals with the construction of some function algebras whose corresponding semigroup compactification are universal with respect to some properies of their enveloping semigroups. the special properties are of beigan a left zero, a left simple, a group, an inflation of the right zero, and an inflation of the rectangular band.

on the comparison of keyword and semantic-context methods of learning new vocabulary meaning

the rationale behind the present study is that particular learning strategies produce more effective results when applied together. the present study tried to investigate the efficiency of the semantic-context strategy alone with a technique called, keyword method. to clarify the point, the current study seeked to find answer to the following question: are the keyword and semantic-context metho...
