A Fast Nonuniform Solver for the Poisson Equation over a Disk
Charlie Pyle, Prabir Daripa
We study fast numerical methods for the Poisson equation on a disk within the FFTRR (Fast Fourier Transform Radial Recurrence) framework, which is built on Green's function represe…

Branched Signature Kernel Solvers for ODEs with rough Single-Trajectory signals
Munawar Ali, Qi Feng, Charlie Pyle +1
We develop a branched signature kernel solver for linear and nonlinear ordinary differential equations driven by a \emph{single observed trajectory} of a possibly rough forcing sig…
