Belyi map verification using certified path tracking

Number Theory 2026-04-20 v1 Algebraic Geometry

Abstract

We provide an end-to-end workflow to rigorously compute the monodromy of Belyi maps from exact equations over number fields using certified homotopy continuation. We then apply this method at scale to certify the monodromy triples of Belyi maps in the LL-functions and Modular Forms Database (LMFDB).
