Ergodic BSDEs and Optimal Ergodic Control in Banach Spaces [PDF]
SIAM Journal on Control and Optimization, 2009 In this paper we introduce a new kind of Backward Stochastic Differential Equations, called ergodic BSDEs, which arise naturally in the study of optimal ergodic control. We study the existence, uniqueness and regularity of solution to ergodic BSDEs. Then we apply these results to the optimal ergodic control of a Banach valued stochastic state equation.

Quantum thermalization: anomalous slow relaxation due to percolation-like dynamics
New Journal of Physics, 2015 We highlight a dynamical anomaly in which the rate of relaxation towards thermal equilibrium in a bi-partite quantum system violates the standard linear-response (Kubo) formulation, even when the underlying dynamics is highly chaotic.

Threshold dynamics of a stochastic mathematical model for Wolbachia infections
Journal of Biological Dynamics, 2023 A stochastic mathematical model is proposed to study how environmental heterogeneity and the augmentation of mosquitoes with [Formula: see text] bacteria affect the outcomes of dengue disease. The existence and uniqueness of the positive solutions of the

MathematicsThis study introduces a wavelet-based framework for estimating derivatives of a general regression function within discrete-time, stationary ergodic processes. The analysis focuses on deriving the integrated mean squared error (IMSE) over compact subsets

Coexistence for a kind of stochastic three-species competitive models
Open Mathematics, 2019 The coexistence of species sustains the ecological balance in nature. This paper focuses on sufficient conditions for the coexistence of a three-species stochastic competitive model, where the model has non-linear diffusion parts.

Ergodic Subspace Analysis [PDF]
Journal of Intelligence, 2020 Properties of psychological variables at the mean or variance level can differ between persons and within persons across multiple time points. For example, cross-sectional findings between persons of different ages do not necessarily reflect the development of a single person over time.

An Ergodic Theorem on Ergodic Transport
, 2015 Here we present an ergodic theorem which adapts a Theorem by J. Elton to the classical thermodynamical formalism and to ergodic transport. First, we discuss how Elton's theorem can be used to characterise Gibbs measures for expanding maps. Such characterisation will be done by constructing a stochastic process, defined by a iterated function system ...

Advanced Functional Materials, EarlyView.Local polar frustration is engineered to stabilize an ergodic relaxer through nanoscale multiphase coexistence, suppressing long‐range ferroelectric order while preserving high polarization. This strategy delivers ultrahigh low‐field normalized energy density (Wa >0.020 mC cm−2), exceptional thermal stability, and a transferable design principle for ...
