Entropy stable high order discontinuous Galerkin methods with suitable quadrature rules for hyperbolic conservation laws
Tianheng Chen,Chi-Wang Shu +1 more
TL;DR: A unified framework for designing high order DG methods which will satisfy entropy inequalities for any given single convex entropy, through suitable numerical quadrature which is specific to this given entropy.
Journal ArticleDOI
Numerical solutions of stochastic PDEs driven by arbitrary type of noise
TL;DR: In this article, the authors proposed a distribution-free Skorokhod-Malliavin calculus framework based on generalized stochastic polynomial chaos expansion and obtained an estimate for the mean square truncation error in the linear case.
Journal ArticleDOI
Certified Offline-Free Reduced Basis (COFRB) Methods for Stochastic Differential Equations Driven by Arbitrary Types of Noise
TL;DR: A new reduced basis method tailored for the linear (ordinary and partial) differential equations driven by arbitrary types of noise, which proposes a new space-time-like treatment of time in the numerical schemes for ODEs and PDEs.
