class triqs.gf.meshes.MeshDLR

Mesh of DLR coefficients

The MeshPoint for a given linear_index i can be otained through m[i] and for an index n through m(n)

The associated Green function allows for evaluation on both arbitrary Matsubara frequencies and tau-points.

Parameters:

  • beta (float) – Inverse temperature

  • statistic (str) – Statistic, ‘Fermion’ or ‘Boson’

  • w_max (float) – DLR energy cutoff, same as Lambda / beta

  • eps (float) – Representation accuracy
