with Measures (IFSm). We study the spectral properties of the Transfer and Markov …

Nonequilibrium in thermodynamic formalism: The second law, gases and information geometry

AO Lopes, R Ruggiero - Qualitative theory of dynamical systems, 2022 - Springer
In nonequilibrium thermodynamics and information theory, the relative entropy (or, KL
divergence) plays a very important role. Consider a Hölder Jacobian J and the Ruelle …

Thermodynamic Formalism for Topological Markov Chains on Borel Standard Spaces

L Cioletti, EA Silva, M Stadlbauer - arXiv preprint arXiv:1810.03757, 2018 - arxiv.org
We develop a Thermodynamic Formalism for bounded continuous potentials defined on the

On information gain, Kullback-Leibler divergence, entropy production and the involution kernel

AO Lopes, JK Mengue - arXiv preprint arXiv:2003.02030, 2020 - arxiv.org
It is well known that in Information Theory and Machine Learning the Kullback-Leibler
divergence, which extends the concept of Shannon entropy, plays a fundamental role. Given …

On the dimension of the space of harmonic functions on transitive shift spaces

L Cioletti, L Melo, R Ruviaro, EA Silva - Advances in Mathematics, 2021 - Elsevier
In this paper, we show a new relation between phase transition in Statistical Mechanics and
the dimension of the space of harmonic functions (SHF) for a transfer operator. This is …

The double transpose of the ruelle operator

L Cioletti, ACD van Enter, R Ruviaro - arXiv preprint arXiv:1710.03841, 2017 - arxiv.org
In this paper we study the double transpose of the $ L^ 1 (X,\mathscr {B}(X),\nu) $-
extensions of the Ruelle transfer operator $\mathscr {L} _ {f} $ associated to a general real …

Thermodynamic Formalism for Haar systems in Noncommutative Integration: transverse functions and entropy of transverse measures

AO Lopes, JK Mengue - Ergodic Theory and Dynamical Systems, 2021 - cambridge.org
We consider here a certain class of groupoids obtained via an equivalence relation (the so-
called subgroupoids of pair groupoids). We generalize to Haar systems in these groupoids …

The Ruelle operator for symmetric -shifts

AO Lopes, V Vargas - 2020 - projecteuclid.org
Consider m∈N and β∈(1,m+1. Assume that a∈R can be represented in base β using a
