jaxvacua.hypergeometric_models

One-modulus hypergeometric Calabi-Yau model registry.

Purpose

Provide hard-coded one-modulus models from Bastian, van de Heisteeg and Schlechter, arXiv:2306.01059, together with closed-form prepotentials at large-complex-structure, K-point and C-point limits.

Main public API

• HypergeometricModels and list_hypergeometric_models for listing and constructing supported models.

• Prepotential builders make_prepot_LCS, make_prepot_Kpoint and make_prepot_Cpoint for low-level custom workflows.

• Registry dictionaries for hypergeometric, non-hypergeometric and special point data.

Design notes

The K-point formula follows equations (1060-1063) of the reference. The C-point formula follows equations (846-849) with the package convention that the instanton normalisation absorbs a factor of (8*pi)^-1 into A1. Models built through this registry use the standard FluxVacuaFinder API.

Factory class

HypergeometricModels()

Static registry + factory for the hardcoded one-modulus CY models from arXiv:2306.01059 (quintics, hypergeometrics, etc.). Construct ready-to-use FluxVacuaFinder instances at LCS, K-point, or C-point boundaries via build().

Closed-form prepotential factories

make_prepot_LCS(kappa, c2, chi)	Return an LCS prepotential callable F(X, conj=False).
make_prepot_Kpoint(tau, gamma, delta, c, B1, ...)	Return a K-point prepotential callable F(X, conj=False).
make_prepot_Cpoint(tau, gamma, delta, k, A1, A2)	Return a C-point prepotential callable F(X, conj=False).

Module-level helpers

list_hypergeometric_models()

Print a summary table of all available models and the moduli-space points at which each has closed-form data. For programmatic use, prefer HypergeometricModels.list().
