An accurate and quadrature-free evaluation of multipole expansion of functions represented by multiwavelets
Jae-Seok Huh
We present formulas for accurate numerical conversion between functions represented by multiwavelets and their multipole/local expansions with respect to the kernel of the form, $e…

Singular quadrature rules and fast convolutions for Fourier spectral methods
Jae-Seok Huh, George Fann
We present a generic scheme to construct corrected trapezoidal rules with spectral accuracy for integral operators with weakly singular kernels in arbitrary dimensions. We assume t…
