A commutative noncommutative fractal geometry [PDF]

, 2011
In this thesis examples of spectral triples, which represent fractal sets, are examined and new insights into their noncommutative geometries are obtained.

Transfer operators for coupled analytic maps [PDF]

, 2000
We consider analytically coupled circle maps (uniformly expanding and analytic) on the ${\mathbb Z}^d$-lattice with exponentially decaying interaction.

Ergodic properties of Kantorovich operators [PDF]

, 2023
Kantorovich operators are non-linear extensions of Markov operators and are omnipresent in several branches of mathematical analysis. The asymptotic behaviour of their iterates plays an important role even in classical ergodic, potential and probability ...

Ergodic properties of operators in some semi-Hilbertian spaces [PDF]

, 2012
This article deals with linear operators T on a complex Hilbert space , which are bounded with respect to the seminorm induced by a positive operator A on .

Linear response theory for magnetic Schrödinger operators in disordered media [PDF]

, 2005
We justify the linear response theory for an ergodic Schrödinger operator with magnetic field within the noninteracting particle approximation, and derive a Kubo formula for the electric conductivity tensor.

Spectral analysis of ergodic Schrödinger operators [PDF]

, 2022
ilustraciones, fotografíasEn este trabajo final de maestría estudiamos los tipos espectrales de las familias de operadores de Schrödinger unidimensionales discretos {Hω}ω∈Ω en las que el potencial de Hω está dado por Vω(n) = f(T nω), para n ∈ Z, donde f :

Ergodic Theory and Averaging Iterations [PDF]

, 1973
Suppose X is a Banach space and T a continuous linear operator on X. The significance of the asymptotic convergence of T for the approximate solution of the equation (I - T)x = f by means of the Picard iterations was clearly shown in Browder's and ...

Recurrence Properties of Hypercyclic Operators [PDF]

, 2016
[EN] We generalize the notions of hypercyclic operators, U-frequently hypercyclic operators and frequently hypercyclic operators by introducing a new concept in linear dynamics, namely A-hypercyclicity.

Chaotic Behaviour on Invariant Sets of Linear Operators [PDF]

, 2015
We study hypercyclicity, Devaney chaos, topological mixing properties and strong mixing in the measure-theoretic sense for operators on topological vector spaces with invariant sets.

Linear transfers, Kantorovich operators, and their ergodic properties [PDF]

, 2020
In this work, we introduce and study a class of convex functionals on pairs of probability measures, the linear transfers, which have a structure that com- monly arises in the dual formulations of many well-studied variational prob- lems. We show that
