A Generalization of Kannan's Fixed Point Theorem

Fixed Point Theory and Applications, 2009
In order to observe the condition of Kannan mappings, we prove a generalization of Kannan's fixed point theorem. Our theorem involves constants and we obtain the best constants to ensure a fixed point.

Fixed points for mappings of cyclical type in ordered metric spaces

, 2013
The purpose of this paper is to present some fixed point results for mappings of cyclical type in the context of ordered metric spaces. Our results extend the ones appearing in [A. Amini-Harandi, H.

Krasnosel'skii fixed point theorem for dissipative operators

Electronic Journal of Differential Equations, 2011
In this note, a sufficient condition guaranteing the existence of fixed points in a nonempty, closed convex K for T+S is given, where $T:Ksubset Eo E$ is dissipative and $S:Ko E$ is condensing.

Ordered Non-Archimedean Fuzzy Metric Spaces and Some Fixed Point Results

, 2010
In the present paper we provide two different kinds of fixed point theorems on ordered nonArchimedean fuzzy metric spaces. First, two fixed point theorems are proved for fuzzy order ψ-contractive type mappings. Then a common fixed point theorem is

A Piecewise-Linear Fixed Point Theorem

The American Mathematical Monthly
We prove that if a continuous piecewise-smooth map on $\mathbb{R}^n$ is comprised of two linear functions, has a bounded orbit, and satisfies a certain non-degeneracy condition, then it has a fixed point. The result has important consequences to the bifurcation theory of nonsmooth dynamical systems, yet the proof requires only elementary linear algebra.

On a fixed point theorem by Totik [PDF]

, 2009
In this paper we prove a common fixed point theorem (see Theorem 3.1) in metric spaces for two self- mappings satisfying a general implicit relation involving the diameter of finite sets, without requiring continuity.
