Distributional chaos for linear operators

open access: yesJournal of Functional Analysis, 2013
We characterize distributional chaos for linear operators on Fréchet spaces in terms of a computable condition (DCC), and also as the existence of distributionally irregular vectors. A sufficient condition for the existence of dense uniformly distributionally irregular manifolds is presented, which is very general and can be applied to many classes of ...

Operator-valued measures and linear operators

open access: yesJournal of Mathematical Analysis and Applications, 2008
AbstractWe study operator-valued measures m:Σ→L(X,Y), where L(X,Y) stands for the space of all continuous linear operators between real Banach spaces X and Y and Σ is a σ-algebra of sets. We extend the Bartle–Dunford–Schwartz theorem and the Orlicz–Pettis theorem for vector measures to the case of operator-valued measures.

Fixed Point Theorems for Middle Point Linear Operators in L1

open access: yesFixed Point Theory and Applications, 2008
We introduce the notion of middle point linear operators. We prove a fixed point result for middle point linear operators in L1. We then present some examples and, as an application, we derive a Markov-Kakutani type fixed point result for commuting ...

An Extension of Hypercyclicity for N-Linear Operators

open access: yesAbstract and Applied Analysis, 2014
Grosse-Erdmann and Kim recently introduced the notion of bihypercyclicity for studying the existence of dense orbits under bilinear operators. We propose an alternative notion of orbit for N-linear operators that is inspired by difference equations ...
