On unrestricted products of (W) contractions

W. Bartoszek (2000)

Colloquium Mathematicae

Similarity:

Given a family of (W) contractions T 1 , . . . , T N on a reflexive Banach space X we discuss unrestricted sequences T r n . . . T r 1 ( x ) . We show that they converge weakly to a common fixed point, which depends only on x and not on the order of the operators T r n if and only if the weak operator closed semigroups generated by T 1 , . . . , T N are right amenable.

On noncompact perturbation of nonconvex sweeping process

Myelkebir Aitalioubrahim (2012)

Commentationes Mathematicae Universitatis Carolinae

Similarity:

We prove a theorem on the existence of solutions of a first order functional differential inclusion governed by a class of nonconvex sweeping process with a noncompact perturbation.
