Generalized multivalued $F$-contractions on non-complete metric spaces
In this paper, we explain a new generalized contractive condition for multivalued mappings and prove a fixed point theorem in metric spaces (not necessary complete) which extends some well-known results in the literature. Finally, as an application, we prove that a multivalued function satisfying a general linear functional inclusion admits a unique selection fulfilling the corresp...
متن کاملCorrection: Nonlinear quasi-contractions in non-normal cone metric spaces
In the note we correct some errors that appeared in the article (Jiang and Li in Fixed Correction Upon critical examination of the main results and their proofs in [], we note some critical errors under the conditions of the main theorem and its proof in our article []. In this note, we would like to supplement some essential conditions, which will ensure that the mapping B is well defined, t...
متن کاملGeneralized multivalued $F$-weak contractions on complete metric spaces
In this paper, we introduce the notion of generalized multivalued $F$- weak contraction and we prove some fixed point theorems related to introduced contraction for multivalued mapping in complete metric spaces. Our results extend and improve the results announced by many others with less hypothesis. Also, we give some illustrative examples.
متن کاملGeneralized multivalued $F$-contractions on complete metric spaces
In the present paper, we introduce the concept of generalized multivalued $F$ -contraction mappings and give a fixed point result, which is a proper generalization of some multivalued fixed point theorems including Nadler's.
متن کاملOn contractions in probabilistic metric spaces
Two types of contractions are used for mappings defined on probabilistic metric spaces. The first type was introduced by V.M. Sehgal [15-16 ], the second type by T.L. Hicks [7]. Since then, many fixed point results were obtained. In this paper we introduce the concept of a probabilistic g−contraction, which is a generalization of a probabilistic contraction of Hicks’ type and prove some fixed p...
