Multivalued self almost local contractions

Annals of the West University of Timisoara: Mathematics and Computer Science, 2019
We introduce a new class of contractive mappings: the almost local contractions, starting from the almost contractions presented by V. Berinde in [V. Berinde, Approximating fixed points of weak contractions using the Picard iteration Nonlinear Analysis ...

On a Nonlinear Integral Equation with Contractive Perturbation [PDF]

Advances in Difference Equations, 2011
Nous obtenons un résultat d'existence pour les solutions à une équation intégrale non linéaire avec perturbation contractive au moyen du théorème du point fixe de Krasnoselskii et surtout de la théorie de la mesure de la non compacité faible.

Nonlinear contractions involving simulation functions in a metric space with a partial order [PDF]

, 2015
Very recently, Khojasteh, Shukla and Radenovic [F. Khojasteh, S. Shukla, S. Radenovic, Filomat, 29 (2015), 1189-1194] introduced the notion of Z-contraction, that is, a nonlinear contraction involving a new class of mappings namely simulation functions ...

A Generalized Nonuniform Contraction and Lyapunov Function

Abstract and Applied Analysis, 2012
For nonautonomous linear equations x′=A(t)x, we give a complete characterization of general nonuniform contractions in terms of Lyapunov functions. We consider the general case of nonuniform contractions, which corresponds to the existence of what we ...

A note on Proinov contraction

Miskolc Mathematical Notes
Proinov contraction has appeared a several years ago as a new approach in the study of nonlinear contractions that unifies and extends several well-known classes of nonlinear contractions. What was not discussed is the relation of Proinov contraction and

Effect of the contraction ratio upon viscoelastic fluid flow in three-dimensional square-square contractions [PDF]

, 2011
In this work we investigate the laminar flow through square–square sudden contractions with various contraction ratios (CR¼2.4, 4,8and12), using a Newtonian fluid and a shear-thinning viscoelastic fluid.
