Local Fokker--Planck Geometry for Score Estimation: Heat-Ball Mean-Value Representations and Exact High-Dimensional Sampling
Jiayao Bai, Lang Deng, Yi Du +1
Score-based generative models and Langevin samplers rely on estimating the score function of a forward diffusion. Classically this is tractable when the drift…

Non-flat Ekman Boundary Layers: Topographic Lift, Generalized Ekman Pumping, and Anisotropic Asymptotic Behavior
Yifei Jia, Yi Du, Lihui Guo
The Ekman boundary layer, a fundamental concept in geophysical fluid mechanics, describes the near-boundary fluid motion subject to rotation. Within the singular limit framework of…

Geometry-dependent Ekman layer approximations on curved domains: L^{\infty} convergence
Yifei Jia, Yi Du, Lihui Guo
The Ekman boundary layer is a fundamental concept in fluid dynamics that describes fluid motion near boundaries affected by Earth's rotation. Most theoretical studies have simplifi…
