The Ultimate Ishii-Pastur Theorem for Whole-Line Ergodic Block Jacobi Operators
Zhenfu Wang, Bei Zhang, Qi Zhou
We establish an ultimate Ishii-Pastur theorem for whole-line ergodic block Jacobi operators. We prove that, for almost every realization, the restriction of a maximal spectral meas…
A Logarithmic Fluctuation Hierarchy for Sequential Interacting Diffusions
Zhenfu Wang, Xianliang Zhao
We study Gaussian fluctuations for a lower-triangular system of interacting diffusions in which particle interacts only with its predecessors. Although the empirical measure of…
Transfer Operators, Canonical Center Dynamics, and Spectral Applications for Long-Range Operators
Xianzhe Li, Zhenfu Wang, Jiangong You +1
We introduce an operator-theoretic framework for long-range operators over general dynamical systems with analytic hopping and small potential. By establishing a partially hyperbol…
Anderson localization of long-range quasi-periodic operators via Dynamical Rigidity
Zhenfu Wang, Jiangong You, Qi Zhou
We establish Anderson localization for long-range quasi-periodic operators with large trigonometric potentials and Diophantine frequencies, the proof is based on a novel dynamical…
On the kinetic equation arising from the large-scale limit of the Cucker-Smale model
Ruicheng Cheng, Seung-Yeal Ha, Jaemoon Lee +1
We propose a large-scale scaling viewpoint for deriving mesoscopic dynamics from interacting particle systems and apply it to the Cucker--Smale flocking model. In contrast with the…
Quantitative Convergence for Sequential Interacting Diffusions via Incremental Relative Entropy
Zhenfu Wang, Xianliang Zhao
We study a lower-triangular system of interacting diffusions in which particle \(i\) interacts only with its predecessors through the empirical measure \(μ^{i-1}_t\). This gives a…
