FMM-accelerated solvers for the Laplace-Beltrami problem on complex surfaces in three dimensions
Dhwanit Agarwal, Michael O'Neil, Manas Rachh
The Laplace-Beltrami problem on closed surfaces embedded in three dimensions arises in many areas of physics, including molecular dynamics (surface diffusion), electromagnetics (ha…

Efficient reduced-rank methods for Gaussian processes with eigenfunction expansions
Philip Greengard, Michael O'Neil
In this work we introduce a reduced-rank algorithm for Gaussian process regression. Our numerical scheme converts a Gaussian process on a user-specified interval to its Karhunen-Lo…
