A space-time dual-pairing summation-by-parts framework for forward and adjoint wave equations
Kenny Wiratama, Kenneth Duru, Yunho Kim
In this paper, we propose the first of its kind space-time dual-pairing summation by parts (DP-SBP) numerical framework for forward and adjoint wave propagation problems. This nove…

A conservative and energy stable discontinuous spectral element method for the shifted wave equation in second order form
Kenneth Duru, Siyang Wang, Kenny Wiratama
In this paper, we develop a provably energy stable and conservative discontinuous spectral element method for the shifted wave equation in second order form. The proposed method co…
