Statistical Limit Theorems for Axiom A Diffeomorphisms: Exponential Mixing, Central Limit Theorem, and Large Deviations

Abdoulaye Thiam

We establish statistical limit theorems for equilibrium states of Axiom A diffeomorphisms, derived from the spectral gap of the Ruelle transfer operator established in Part I (Thia…

Transfer Operators and SRB Measures for Axiom A Diffeomorphisms: Spectral Gap, Structural Stability, and the Gibbs Equivalence Theorem

Abdoulaye Thiam

We develop the Ruelle transfer operator theory for Axiom A diffeomorphisms and construct Sinai-Ruelle-Bowen measures, carrying the symbolic spectral results of Part I [64] over to…

Mixed Global Dynamics of the Forced Vibro-Impact Oscillator with Coulomb Friction and its Symplectic Structure, KAM Tori, and Persistence

Abdoulaye Thiam

The forced vibro-impact oscillator with Amonton-Coulomb friction and elastic walls was shown by Gendelman et al. (2019) to exhibit a coexistence of Hamiltonian stability islands an…

Quantitative Analyticity for Lyapunov Exponents of Random Products of Matrices with Explicit Polydiscs and Cauchy Coefficient Bounds

Abdoulaye Thiam

The top Lyapunov exponent of a random product of matrices in , , with simple top spectrum, depends real-analytically on the proba…

Quantitative Hölder Regularity, Concentration, and Spectral Applications for Lyapunov Exponents of Random Cocycles, with Extensions to

Abdoulaye Thiam

This paper develops a quantitative regularity theory for the Lyapunov exponents of random products of matrices in , with extensions to $\operatorna…

Multifractal Analysis, Livšic Rigidity, and Fluctuation Theorems for Axiom A Diffeomorphisms: The Pesin Formula and the Gallavotti-Cohen Symmetry

Abdoulaye Thiam

This Part develops structural consequences of the thermodynamic formalism for Axiom A diffeomorphisms. The Pesin Entropy Formula equates the metric entropy of the SRB measure to th…
