Coincidence points of generalized multivalued (f,L)-almost F-contraction with applications

Abbas, Mujahid; Ali, Basit; Romaguera Bonilla, Salvador (INT SCIENTIFIC RESEARCH PUBLICATIONS, 2015)

Common fixed points of Ciric-type contractions on partial metric spaces

Abbas, Mujahid; Altun, Ishak; Romaguera Bonilla, Salvador (Debreceni Egyetem, Matematika Intézet, 2013)

We obtain a common fixed point theorem of Boyd-Wong type for four mappings satisfying a Ciric-type contraction on a complete partial metric space. Our result generalizes and unifies, among others, the very recent results ...

Fixed points of fuzzy soft mappings

Abbas, Mujahid; Khalid, Asma; Romaguera Bonilla, Salvador (Natural Sciences Publishing, 2014-09)

[EN] In this paper, the concept of a fuzzy soft mapping on a fuzzy soft set is introduced and the study of fixed points of such mappings is initiated.
Generalized c-distance on cone b-metric spaces endowed with a graph and fixed point results

Fallahi, Kamal; Abbas, Mujahid; Soleimani Rad, Ghasem (Universitat Politècnica de València, 2017-10-02)

[EN] The aim of this paper is to present fixed point results of contractive mappings in the framework of cone b-metric spaces endowed with a graph and associated with a generalized c-distance. Some corollaries and an example ...
Generalized Contraction and Invariant Approximation Resultson Nonconvex Subsets of Normed Spaces

Abbas, Mujahid; Ali, Basit; Romaguera Bonilla, Salvador (Hindawi Publishing Corporation, 2014)

Wardowski (2012) introduced a new type of contractive mapping and proved a fixed point result in complete metric spaces as a generalization of Banach contraction principle. In this paper, we introduce a notion of generalized ...
Generalized Operations in Soft Set Theory via Relaxed Conditions on Parameters

Abbas, Mujahid; Ali, Muhammad Irfan; Romaguera Bonilla, Salvador (National Library of Serbia, 2017)

[EN] Soft set theory has been evolved as a very useful mathematical tool to handle uncertainty and ambiguity associated with the real world data based structures. Parameters with certain conditions have been used to classify ...
