Immersed Spheres of Finite Total Curvature into Manifolds [PDF]

open access: yes, 2013
We prove that a sequence of possibly branched, weak immersions of the two-sphere $S^2$ into an arbitrary compact riemannian manifold $(M^m,h)$ with uniformly bounded area and uniformly bounded $L^2-$norm of the second fundamental form either collapse to ...

Convergence theorems for generalized nonexpansive mappings in uniformly convex Banach spaces

open access: yesFixed Point Theory and Applications, 2015
In this paper, we prove strong and weak convergence theorems for a mapping defined on a bounded, closed and convex subset of a uniformly convex Banach space, satisfying the RCSC condition. This condition was introduced by Karapınar (Dynamical Systems and

Stable commutator length on mapping class groups [PDF]

open access: yes, 2013
Let $\Gamma$ be a finite index subgroup of the mapping class group $MCG(\Sigma)$ of a closed orientable surface $\Sigma$, possibly with punctures. We give a precise condition (in terms of the Nielsen-Thurston decomposition) when an element $g\in\Gamma ...

An Iterative Algorithm on Approximating Fixed Points of Pseudocontractive Mappings

open access: yesJournal of Applied Mathematics, 2012
Let E be a real reflexive Banach space with a uniformly Gâteaux differentiable norm. Let K be a nonempty bounded closed convex subset of E, and every nonempty closed convex bounded subset of K has the fixed point property for non-expansive self-mappings.

Viscosity Methods of Asymptotically Pseudocontractive and Asymptotically Nonexpansive Mappings for Variational Inequalities

open access: yesAbstract and Applied Analysis, 2012
Let {𝑡𝑛}⊂(0,1) be such that 𝑡𝑛→1 as 𝑛→∞, let 𝛼 and 𝛽 be two positive numbers such that 𝛼+𝛽=1, and let 𝑓 be a contraction. If 𝑇 be a continuous asymptotically pseudocontractive self-mapping of a nonempty bounded closed convex subset 𝐾 of a real reflexive ...

Approximation of fixed points of strongly pseudocontractive mappings in uniformly smooth Banach spaces

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2006
Let E be a real uniformly smooth Banach space, and K a nonempty closed convex subset of E. Assume that T1+T2: K→K is a continuous and strongly pseudocontractive mapping, where T1:K→K is Lipschitz and T2:K→K has the bounded range mapping.

Convergence theorems for fixed points of demicontinuous pseudocontractive mappings

open access: yesFixed Point Theory and Applications, 2005
Let D be an open subset of a real uniformly smooth Banach space E. Suppose T:D¯→E is a demicontinuous pseudocontractive mapping satisfying an appropriate condition, where D¯ denotes the closure of D.

Uniformly Lipschitzian mappings in modular function spaces [PDF]

open access: yes, 2001
Let ρ be a convex modular function satisfying a ∆2-type condition and Lρ the corresponding modular space. Assume that C is a ρ-bounded and ρ-a.e compact subset of Lρ and T : C → C is a k-uniformly Lipschitzian mapping.
