Python-script for computing the values of small diagrams in the Gaudin-Gillespie-Ripka (GGR) expansion.
The GGR expansion is explained in the papers:
- Almost optimal upper bound for the ground state energy of a dilute Fermi gas via cluster expansion
A. B. Lauritsen, arXiv:2301.08005
- Ground state energy of the dilute spin-polarized Fermi gas: Upper bound via cluster expansion
A. B. Lauritsen and R. Seiringer, J. Funct. Anal. 286.7 (2024), 110320, arXiv:2301.04894,
The script takes as input a graph and outputs all equivalence classes of quasi-linked permutations, meaning permutations with each linked component having at least one external vertex.
Two permutations/diagrams are equivalent if they have the same value. This happens if the permutations are related by a symmetry of the graph. For each equivalence class is computed the weight being the sign times the number of equivalent permutations in the equivalence class.
