A Method for Computing Inverse Parametric PDE Problems with Random-Weight Neural Networks
Suchuan Dong, Yiran Wang
We present a method for computing the inverse parameters and the solution field to inverse parametric PDEs based on randomized neural networks. This extends the local extreme learn…

Recovery of black hole mass from a single quasinormal mode
Gunther Uhlmann, Yiran Wang
We study the determination of the mass of a de Sitter-Schwarzschild black hole from one quasinormal mode. We prove a local uniqueness result with a Hölder type stability estimate.

A conservative multiscale method for stochastic highly heterogeneous flow
Yiran Wang, Eric Chung, Shubin Fu
In this paper, we propose a local model reduction approach for subsurface flow problems in stochastic and highly heterogeneous media. To guarantee the mass conservation, we conside…
