class triqs_Nevanlinna.solver_core.SolverCore

Bases: object

Nevanlinna analytical continuation solver for TRIQS Green’s functions.

Performs analytical continuation for the diagonal part of the matrix-values TRIQS Green’s function.

---

Dispatched C++ constructor(s).

[1] (p: NevanlinnaParametersT)

Construct the solver.

Parameters:

pNevanlinnaParametersT

Construction parameters (kernel choice and multiprecision precision).

Attributes

Pick_eigenvalues

Eigenvalues of the Pick matrix (non-negative eigenvalues indicate the data is continuable).

Methods

evaluate	Evaluate diagonal part of the real-frequency Green's function on a chosen grid.
solve	Perform a Nevanlinna factorization for a matrix-valued Matsubara frequency Green's function.
