Adaptive Uncertainty Quantification for Stochastic Hyperbolic Conservation Laws

JJ Harmon, S Tokareva, A Zlotnik, PJ Swart - arXiv preprint arXiv …, 2024 - arxiv.org
We propose a predictor-corrector adaptive method for the study of hyperbolic partial
differential equations (PDEs) under uncertainty. Constructed around the framework of …

We present a multi-level Monte Carlo (MLMC) algorithm with adaptively refined meshes and
accurately computed stopping-criteria utilizing adjoint-based a posteriori error analysis for …

Error estimation for the time to a threshold value in evolutionary partial differential equations

JH Chaudhry, D Estep, T Giannini, Z Stevens… - BIT Numerical …, 2023 - Springer
We develop an a posteriori error analysis for a numerical estimate of the time at which a
functional of the solution to a partial differential equation (PDE) first achieves a threshold …
