Abstract

We present an algorithmic way of exactly computing Belyi functions for hypermaps and triangulations in genus $0$ or $1$, and the associated dessins, based on a numerical iterative approach initialized from a circle packing combined with subsequent lattice reduction. The main advantage compared to previous methods is that it is applicable to much larger graphs; we use very little algebraic geometry, and aim for this paper to be as self-contained as possible.
