AAA-least squares rational approximation and solution of Laplace problems
Stefano Costa, Lloyd N. Trefethen
A two-step method for solving planar Laplace problems via rational approximation is introduced. First complex rational approximations to the boundary data are determined by AAA app…

Solving Laplace problems with the AAA algorithm
Stefano Costa
We present a novel application of the recently developed AAA algorithm to the solution of Laplace 2D problems; an application to conformal mapping is also shown as a particular cas…

An efficient procedure for solving potential field problems: the Conformal Boundary Differences Method
Stefano Costa
A novel method rooted in the classical Schwarz-Christoffel transformation from the disk is introduced, which allows for fast and accurate solution of potential field problems in po…
