Computation of two-dimensional stokes flows via lightning and AAA rational approximation

Y Xue, SL Waters, LN Trefethen - SIAM Journal on Scientific Computing, 2024 - SIAM
Low Reynolds number fluid flows are governed by the Stokes equations. In two dimensions,
Stokes flows can be described by two analytic functions, known as Goursat functions …

Representation of conformal maps by rational functions

A Gopal, LN Trefethen - Numerische Mathematik, 2019 - Springer
The traditional view in numerical conformal mapping is that once the boundary
correspondence function has been found, the map and its inverse can be evaluated by …

Crystals (LC). Here, the fact is utilised that LC feature at GHz frequencies as well as at …

The AAAtrig algorithm for rational approximation of periodic functions

PJ Baddoo - SIAM Journal on Scientific Computing, 2021 - SIAM
We present an extension of the AAA (adaptive Antoulas--Anderson) algorithm for periodic
functions, called “AAAtrig.” The algorithm uses the key steps of AAA approximation by (i) …
