On the discrete Poincaré inequality for B-schemes of 1D Fokker-Planck equations in full space
Journal Article Quarterly of Applied Mathematics · March 4, 2026 In this paper, we propose two approaches to derive the discrete PoincarĂ© inequality for the B-schemes, a family of finite volume discretization schemes, for the one-dimensional Fokker-Planck equation in full space. We study the properties of the spatial ... Full text CiteConvergence of Random Batch Method with replacement for interacting particle systems
Journal Article Mathematics of Computation · February 27, 2026 The Random Batch Method (RBM) proposed by [J. Comput. Phys. 400 (2020), p. 30] is an efficient algorithm for simulating interacting particle systems (IPS). In this paper, we investigate the Random Batch Method with replacement (RBM- ... Full text CiteData assimilation models for computing probability distributions of complex multiscale systems
Journal Article Journal of Computational Physics · January 15, 2026 We introduce a data assimilation strategy aimed at accurately capturing key non-Gaussian structures in probability distributions using a small ensemble size. A major challenge in statistical forecasting of nonlinearly coupled multiscale systems is mitigati ... Full text CiteRecent Grants
