Fourier-Galerkin method for scattering poles of sound soft obstacles
Yunyun Ma, Jiguang Sun
The computation of scattering poles for a sound-soft obstacle is investigated. These poles correspond to the eigenvalues of two boundary integral operators. We construct novel deco…
Operator Inference for Elliptic Eigenvalue Problems
Haoqian Li, Jiguang Sun, Zhiwen Zhang
Eigenvalue problems for elliptic operators play an important role in science and engineering applications, where efficient and accurate numerical computation is essential. In this…
FEM-DtN-SIM Method for Computing Resonances of Schrödinger Operators
Bo Gong, Takumi Sato, Jiguang Sun +1
The study of resonances of the Schrödinger operator has a long-standing tradition in mathematical physics. Extensive theoretical investigations have explored the proximity of reso…
