Nonlinear proximinal multivalued contractions on quasi-metric spaces

, 2017
Altun, Ishak/0000-0002-7967-0554In 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

Conjugacies between general contractions

, 2012
The main aim of this note is to construct topological conjugacies between linear nonautonomous contractions with discrete time. As a consequence, we obtain topological conjugacies between linear and nonlinear nonautonomous contractions.

On the covering dimension of the set of solutions of some nonlinear equations [PDF]

, 1986
We prove an abstract theorem whose sole hypothesis is that the degree of a certain map is nonzero and whose parametric equations are studied using cohomological mconclusions imply sharp, multidimensional continuation results.

Three-Point Boundary Value Problems of Nonlinear Second-Order q-Difference Equations Involving Different Numbers of q

Journal of Applied Mathematics, 2013
We study a new class of three-point boundary value problems of nonlinear second-order q-difference equations. Our problems contain different numbers of q in derivatives and integrals.

Nonlinear Contractions and Semigroups in Complete Fuzzy Metric Spaces [PDF]

, 2013
Our main purpose in this paper is to introduce the notion of φ-contractive mapping in fuzzy metric spaces and to present two new results on the existence and the approximation of fixed point of nonlinear contractions mappings and semigroups in fuzzy ...

The method of differential contractions

, 2014
In this Note we present a general and fairly simple method to design families of contractions for nonlinear partial differential equations, either of evolution type, or of stationary type.

A Fixed Point Framework for Nonlinear Fractional Systems with Memory Effects

Fractal and Fractional
In this work, we develop two new classes of rational contraction mappings along with the corresponding fixed point theorems for these types of contractions in suprametric spaces.

Exploring fixed points via admissibility criteria for fuzzy theta f-weak contractions

In this study, we introduce a new class of fuzzy contractions, called fuzzy α-η-θf -weak contractions, and establish fixed point results within the framework of complete fuzzy metric spaces.
