Fractal and Fractional, 2022 The aim of this paper is to obtain some new results about common fixed points. Our results use weaker conditions than those previously used. We have relaxed the conditions for commutating pair mappings and compatible mappings of the type (A), which were ...

FIXED POINT THEOREMS OF FUZZY SET-VALUED MAPS WITH APPLICATIONS
Проблемы анализа, 2020 In this paper, we introduce the notion of Suzuki-type (𝛼, 𝛽)-weak contractions in the setting of fuzzy set-valued maps, thereby establishing some fuzzy fixed point theorems. Moreover, one of our theorems is applied to study a homotopy result.

Fixed points of hesitant fuzzy set-valued maps with applications
Karpatsʹkì Matematičnì Publìkacìï, 2021 In this paper, the notion of hesitant fuzzy fixed points is introduced. To this end, we define Suzuki-type $(\alpha,\beta)$-weak contractions in the framework of hesitant fuzzy set-valued maps, thereby establishing some corresponding fixed point theorems.

Results in Nonlinear Analysis, 2021 In this paper, we construct a new hybrid iteration, called SR-iteration, and prove its stability and convergence analysis for weak contraction mappings in a Banach space.

Best Proximity Point Results for Almost Contraction and Application to Nonlinear Differential Equation [PDF]
Sahand Communications in Mathematical Analysis, 2020 Berinde [V. Berinde, Approximating fixed points of weak contractions using the Picard iteration, Nonlinear Anal. Forum {bf 9} (2004), 43-53] introduced almost contraction mappings and proved Banach contraction principle for such mappings. The aim of this

Convergence Comparison of Several Iteration Algorithms for the Common Fixed Point Problems
Fixed Point Theory and Applications, 2009 We discuss the following viscosity approximations with the weak contraction A for a non-expansive mapping sequence {Tn}, yn=αnAyn+(1−αn)Tnyn, xn+1=αnAxn+(1−αn)Tnxn.

An Extension of Generalized -Weak Contractions [PDF]
International Journal of Mathematics and Mathematical Sciences, 2012 We prove a fixed-point theorem for a class of maps that satisfy generalized -weak contractions depending on a given function. An example is given to illustrate our extensions.

Solution of fractional integral equations via fixed point results
Journal of Inequalities and Applications, 2022 In this paper, we introduce two new concepts of F-contraction, called dual F ∗ $F^{*}$ -weak contraction and triple F ∗ $F^{*}$ -weak contraction, which generalize the existing contractions in the sense of Wardowski, Jleli and Samet as well as Skof ...

Fixed Points and λ-Weak Contractions
Symmetry, 2023 In this paper, we introduce a new type of contractions on a metric space (X,d) in which the distance d(x,y) is replaced with a function, depending on a parameter λ, that is not symmetric in general. This function generalizes the usual case when λ=1/2 and can take bigger values than m1/2.

Dark Matter Contraction and the Stellar Content of Massive Early-type Galaxies: Disfavoring "Light" Initial Mass Functions [PDF]
, 2010 We use stellar dynamics, strong lensing, stellar population synthesis models, and weak lensing shear measurements to constrain the dark matter (DM) profile and stellar mass in a sample of 53 massive early-type galaxies.
