Fixed Points of Multivalued Maps in Modular Function Spaces

Fixed Point Theory and Applications, 2009
The purpose of this paper is to study the existence of fixed points for contractive-type and nonexpansive-type multivalued maps in the setting of modular function spaces. We also discuss the concept of w-modular function and prove fixed point results for

Modular function of long noncoding RNA, COLDAIR, in the vernalization response. [PDF]

PLoS Genet, 2017
The long noncoding RNA COLDAIR is necessary for the repression of a floral repressor FLOWERING LOCUS C (FLC) during vernalization in Arabidopsis thaliana.

Iterative Approximation of Fixed Point of Multivalued ρ-Quasi-Nonexpansive Mappings in Modular Function Spaces with Applications

Journal of Function Spaces, 2018
Recently, Khan and Abbas initiated the study of approximating fixed points of multivalued nonlinear mappings in modular function spaces. It is our purpose in this study to continue this recent trend in the study of fixed point theory of multivalued ...

A Korovkin theorem in multivariate modular function spaces

Journal of Function Spaces and Applications, 2009
In this paper a modular version of the classical Korovkin theorem in multivariate modular function spaces is obtained and applications to some multivariate discrete and integral operators, acting in Orlicz spaces, are given.

KKM and KY fan theorems in modular function spaces

Fixed Point Theory and Applications, 2011
In modular function spaces, we introduce Knaster-Kuratowski-Mazurkiewicz mappings (in short KKM-mappings) and prove an analogue to Ky Fan s fixed point theorem. 2010 Mathematics Subject Classification: Primary 46B20, 47H09; Secondary 47H10.

Singular anisotropic equations with a sign-changing perturbation

Nonlinear Analysis, 2023
We consider an anisotropic Dirichlet problem driven by the variable (p, q)-Laplacian (double phase problem). In the reaction, we have the competing effects of a singular term and of a superlinear perturbation. Contrary to most of the previous papers, we

Singular moduli of rth Roots of modular functions

Open Mathematics, 2023
When singular moduli of Hauptmodules generate ring class fields (resp. ray class fields) of imaginary quadratic fields, using the theory of Shimura reciprocity law, we determine a necessary and sufficient condition for singular moduli of rrth roots of ...

A double phase equation with convection

Electronic Journal of Qualitative Theory of Differential Equations, 2021
We consider a double phase problem with a gradient dependent reaction (convection). Using the theory of nonlinear operators of monotone type, we show the existence of a nontrivial, positive, bounded solution.

Approximation of fixed point of multivalued ρ-quasi-contractive mappings in modular function spaces [PDF]

Arab Journal of Mathematical Sciences, 2020
The purpose of this paper is to extend the recent results of Okeke et al. (2018) to the class of multivalued ρ-quasi-contractive mappings in modular function spaces.

Approximating fixed points of $$\left( \lambda ,\rho \right) $$λ,ρ-firmly nonexpansive mappings in modular function spaces [PDF]

, 2018
In this paper, we first introduce an iterative process in modular function spaces and then extend the idea of a $$\lambda $$λ-firmly nonexpansive mapping from Banach spaces to modular function spaces.
