A Nonuniform Fast Hankel Transform

Paul G. Beckman, Michael O'Neil

We describe a fast algorithm for computing discrete Hankel transforms of moderate orders from $n$ nonuniform points to $m$ nonuniform frequencies in $O ((m + n) lo g min (n, m))$ operati…

A parametrix method for elliptic surface PDEs

Tristan Goodwill, Michael O'Neil

Elliptic problems along smooth surfaces embedded in three dimensions occur in thin-membrane mechanics, electromagnetics (harmonic vector fields), and computational geometry. In thi…
