triqs.gfs.gf

Generic Green’s function container (Gf).

This module defines Gf, the canonical container for any TRIQS quantity indexed by a mesh and a target space (Green’s functions, self-energies, hybridization functions, …). The class inherits a set of C++-backed methods from triqs.gfs.gf_fnt via the AddMethod metaclass; pure-Python methods (arithmetic, slicing, lazy initialization) are defined directly here.

Functions

add_method_helper(a, cls)	Wrap a free function a(self, ...) as an unbound method.
bckwd(hdf_scheme)	Map a legacy GfXxx HDF5 scheme name to the constructor kwargs for the current Gf class.
call_factory_from_dict(cl, name, dic)	Factory used by HDF5 IO.

Classes

AddMethod(name, bases, dct)	Metaclass that injects every callable in triqs.gfs.gf_fnt as a Gf method.
CallProxyNone(*args)	Fallback for __call__() when no compiled C++ proxy fits the Gf.
Gf(**kw)	Container for Green's functions and related quantities.
Idx(*x)	Tag wrapping a mesh-point linear index for use in Gf [] access.
