Fast adjoint algorithm for linear responses of hyperbolic chaos

A Ni - SIAM Journal on Applied Dynamical Systems, 2023 - SIAM
We develop an algorithm for the equivariant divergence formula of the unstable perturbation
of unstable transfer operators, by progressively computing many bounded vectors or …

A rigorous computational approach to linear response

W Bahsoun, S Galatolo, I Nisoli, X Niu - Nonlinearity, 2018 - iopscience.iop.org
We present a general setting in which the formula describing the linear response of the
physical measure of a perturbed system can be obtained. In this general setting we obtain …

Convergence and Approximation of Invariant Measures for Neural Field Lattice Models under Noise Perturbation

T Caraballo, Z Chen, L Li - SIAM Journal on Applied Dynamical Systems, 2024 - SIAM
This paper is mainly concerned with limiting behaviors of invariant measures for neural field
lattice models in a random environment. First of all, we consider the convergence relation of …

Spectral Galerkin methods for transfer operators in uniformly expanding dynamics

C Wormell - Numerische Mathematik, 2019 - Springer
Markov expanding maps, a class of simple chaotic systems, are commonly used as models
for chaotic dynamics, but existing numerical methods to study long-time statistical properties …

Existence of noise induced order, a computer aided proof

S Galatolo, M Monge, I Nisoli - Nonlinearity, 2020 - iopscience.iop.org
We prove the existence of noise induced order in the Matsumoto–Tsuda model, where it was
originally discovered in 1983 by numerical simulations. This is a model of the famous …

Whitney–Hölder continuity of the SRB measure for transversal families of smooth unimodal maps

V Baladi, M Benedicks, D Schnellmann - Inventiones mathematicae, 2015 - Springer
We consider C^ 2 C 2 families t ↦ f_t t↦ ft of C^ 4 C 4 nondegenerate unimodal maps. We
study the absolutely continuous invariant probability (SRB) measure μ _t μ t of f_t ft, as a …

Equivariant divergence formula for hyperbolic chaotic flows

A Ni, Y Tong - Journal of Statistical Physics, 2024 - Springer
We prove the equivariant divergence formula for axiom A flow attractors. It is a pointwisely-
defined and recursive formula for perturbation of SRB measures along center-unstable …

Lagrange approximation of transfer operators associated with holomorphic data

OF Bandtlow, J Slipantschuk - arXiv preprint arXiv:2004.03534, 2020 - arxiv.org
We show that spectral data of transfer operators given by holomorphic data can be
approximated using an effective numerical scheme based on Lagrange interpolation. In …

Approximating linear response by nonintrusive shadowing algorithms

A Ni - SIAM Journal on Numerical Analysis, 2021 - SIAM
Nonintrusive shadowing algorithms efficiently compute v, the difference between shadowing
trajectories, and then use v to compute derivatives of averaged objectives of chaos with …
