A Random Evolution Inclusion of Subdifferential Type in Hilbert Spaces [PDF]

open access: yes, 1996
In this paper we study a nonlinear evolution inclusion of subdifferential type in Hilbert spaces. The perturbation term is Hausdorff continuous in the state variable and has closed but not necessarily convex values.

Convergence comparison and stability of Jungck-Kirk-type algorithms for common fixed point problems

open access: yes, 2013
The aim of this article is to introduce new hybrid iterative schemes, namely Jungck-Kirk-SP and Jungck-Kirk-CR iterative schemes, and prove convergence and stability results for these iterative schemes using certain quasi-contractive operators. Numerical

Mann iteration for generalized pseudocontractive maps in Hilbert spaces [PDF]

open access: yes, 2001
If X is a real Hilbert space, B is a nonempty, bounded, convex and closed subset, T:B→ B is a generalized pseudocontraction; then the iteration begin{eqnarray} x_{1} &in &B, \ x_{n+1} &=&(1-alpha _{n})x_{n}+alpha _{n}Tx_{n}, nonumber \ (alpha _{n})_{n} &

A modified Mann iteration for zero points of accretive operators

open access: yes, 2013
A modified Mann iteration with computational errors is investigated. A strong convergence theorem for zero points of an m-accretive operator is established in a Banach space.MSC:47H06, 47H09, 47J25, 65J15.

Convergence of Ishikawa iterative sequence for strongly pseudocontractive operators in arbitrary Banach spaces [PDF]

open access: yes, 2010
Under the condition of removing the restriction any bounded, we give the convergence of the Ishikawa iteration process to a unique fixed point of a strongly pseudocontractive operator in arbitrary real Banach space.

Stability of Mann and Ishikawa iterative processes with errors for a class of nonlinear variational inclusions [PDF]

open access: yes, 2004
Under the lack of the condition , some new convergence and stability theorems of Mann and Ishikawa iterative processes with errors for solutions to variational inclusions involving accretive mappings in real reflexive Banach spaces are established.

Convergence and stability of Jungck-type iterative procedures in convex b-metric spaces

open access: yes, 2013
The purpose of this paper is to investigate some strong convergence as well as stability results of some iterative procedures for a special class of mappings.

Quantum dynamical semigroups for diffusion models with Hartree interaction

open access: yes, 2004
We consider a class of evolution equations in Lindblad form, which model the dynamics of dissipative quantum mechanical systems with mean-field interaction. Particularly, this class includes the so-called Quantum Fokker-Planck-Poisson model.

Metrical common fixed point theorems without completeness and closedness

open access: yes, 2012
In this article, we point out that some recent results proved in Babu and Alemayehu are corollaries of the main result of an article due to Ali and Imdad.
