Lyapunov-type inequalities for a fractional p-Laplacian equation
(Springeropen, 2016)
In this paper, we present new Lyapunov-type inequalities for a fractional boundary value problem that models a turbulent flow in a porous medium. The obtained inequalities are used to obtain a lower bound for the eigenvalues ...
Multivalued Pseudo-Picard Operators and Fixed Point Results
(Hindawi Ltd, 2013)
We introduce the concept of multivalued pseudo-Picard (MPP) operator on ametric space. This concept is weaker than multivalued weakly Picard (MWP) operator, which is given by M. Berinde and V. Berinde (2007). Then, we give ...
On Nonlinear Set-Valued theta-Contractions
(MALAYSIAN MATHEMATICAL SCIENCES SOC, 2020)
In this paper, we introduce and study new fixed point results for nonlinear set-valued theta-contractions. Our results are based on a new approach, which is called set-valued theta-contraction and they extend and generalize ...
Fixed point results for multivalued mappings of Ciric type via F-contractions on quasi metric spaces
(DE GRUYTER POLAND SP Z O O, 2020)
In this paper, we present some fixed point results for multivalued mappings with both closed values and proximinal values on left K-complete quasi metric spaces. We also provide a nontrivial example to illustrate our results.
Fixed points of F-contractive type fuzzy mappings
(Ios Press, 2017)
In this paper, taking into account the recent contractive technique, which was introduced by Wardowski [18], we present a fixed point theorem for F-contractive type fuzzy mappings over a complete metric space.
Nonlinear proximinal multivalued contractions on quasi-metric spaces
(Springer Basel Ag, 2017)
In this paper, taking into account the concept of proximinal set, we obtain some new fixed point results for nonlinear proximinal multivalued contractions on some kind of complete quasi-metric spaces. Also, we present some ...
A new approach to the Assad-Kirk fixed point theorem
(Springer Basel Ag, 2016)
In the present paper, considering the Wardowski's technique, we give a new approach to the Assad-Kirk fixed point theorem on metrically convex metric spaces. We also provide a nontrivial example showing that our result is ...
Fixed point and homotopy results for multivalued maps satisfying an implicit relation
(Birkhauser Verlag Ag, 2011)
We present some common fixed point theorems for multivalued maps satisfying an implicit relation on complete metric spaces. Also a homotopy result is given for multivalued maps.
Fixed Point Results for F-contractions on Space with Two Metrics
(Univ Nis, Fac Sci Math, 2017)
In this paper, taking into account two metrics on a space, we present a new fixed point theorem for F-contractions. Our theorem includes both Agarwal and O'Regan's and Wardowski's results as properly. Also we provide a ...
Fixed Point Results for α-ψ-Contractive Mappings Including Almost Contractions and Applications
(Hindawi Publishing Corp, 2014)
In the recent paper (B. Samet, C. Vetro, and P. Vetro, Fixed point theorems for alpha-psi-contractive type mappings, Nonlinear Analysis. Theory, Methods and Applications, 75 (2012), 2154-2165.), the authors introduced the ...
