A Homotopy Theory for Maps Having Strongly Convexly Totally Bounded Ranges in Topological Vector Spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
This paper presents Leray–Schauder alternatives and a topological transversality (homotopy) theorem for compact upper semicontinuos maps having (strongly) convexly totally bounded ranges.

Wendroff type inequalities on time scales via Picard operators

, 2013
Recently (see [11]) R.A.C. Ferreira, D.F.M. Torres proved some linear and nonlinear Wendroff type inequalities on time scales. Similar results were proved also by D.R. Anderson ([2] and [3]). It is well known (see [9]) that the Wendroff inequality is not

Fixed point iterations for Prešić-Kannan nonexpansive mappings in product convex metric spaces

Acta Universitatis Sapientiae: Mathematica, 2018
We introduce Prešić-Kannan nonexpansive mappings on the product spaces and show that they have a unique fixed point in uniformly convex metric spaces. Moreover, we approximate this fixed point by Mann iterations. Our results are new in the literature and

Strong convergence of a composite Halpern-type iteration for a family of nonexpansive mappings in CAT(0) spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2017
In this paper, we prove the strong convergence of the composite Halpern-type iteration for a family of nonexpansive mappings in CAT(0) spaces and compare our results with several recent results in this subject.

Existence results for an impulsive neutral integro-differential equations in Banach spaces

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2019
In this manuscript we investigate the existence of mild solution for a abstract impulsive neutral integro-differential equation by using semi-group theory and Krasnoselskii-Schaefer fixed point theorem in different approach.

An extragradient iterative scheme for common fixed point problems and variational inequality problems with applications

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2015
In this paper, by combining a modified extragradient scheme with the viscosity approximation technique, an iterative scheme is developed for computing the common element of the set of fixed points of a sequence of asymptotically nonexpansive mappings and
