Hierarchical low-rank compression exploiting symmetric boundary integral equations in transmission scattering

Yasuhiro Matsumoto, Taizo Maruyama, Qianxiang Ma +1

We propose an approach using matrix symmetry to accelerate hierarchical low-rank compression for wave transmission scattering. For Helmholtz transmission problems, we introduce a s…
