Library for discrete Lehmann representation of imaginary time Green's functions

libdlr: Imaginary time calculations using the Discrete Lehmann Representation (DLR)

Authors: Jason Kaye and Hugo UR Strand (2021)

libdlr is a library providing Fortran subroutines to build and work with the discrete Lehmann representation for single particle imaginary time Green's functions, as well as the stand-alone Python module pydlr implementing the same functionality.

For more information see the documentation.
