Package for analytic continuation of many-body Green's functions
Contains routines for rational interpolation of functions
Exploring the phenomenological applications of rational approximations, such as Padé approximants, to estimate axial mass and radius of nucleons using experimental (quasistatic neutrino-nucleon scattering) and Lattice QCD data.
Python package to parametrise the multi-channel S-matrix using a pade approximation according to the technique presented in "S.A. Rakityansky P.O.G. Ogunbade. S-matrix parametrization as a way of locating quantum resonances and bound states:multichannel case, 2010".
A Fortran library for performing rational approximation of functions.
Add a description, image, and links to the pade-approximation topic page so that developers can more easily learn about it.
