Learning based numerical methods for Helmholtz equation with high frequency
Yu Chen, Jin Cheng, Tingyue Li +1
High-frequency issues have been remarkably challenges in numerical methods for partial differential equations. In this paper, a learning based numerical method (LbNM) is proposed f…

Hadamard integrator for time-dependent wave equations: Lagrangian formulation via ray tracing
Yuxiao Wei, Jin Cheng, Robert Burridge +1
We propose a novel Hadamard integrator for the self-adjoint time-dependent wave equation in an inhomogeneous medium. First, we create a new asymptotic series based on the Gelfand-S…
