A kernel-independent treecode based on barycentric Lagrange interpolation

6 Feb 2019 Lei Wang Robert Krasny Svetlana Tlupova

A kernel-independent treecode (KITC) is presented for fast summation of pairwise particle interactions. In general, treecodes replace the particle-particle interactions by particle-cluster interactions, and here we utilize barycentric Lagrange interpolation at Chebyshev points to compute well-separated particle-cluster interactions...
