Computing Euclidean Belyi maps
Journal de théorie des nombres de Bordeaux, Tome 35 (2023) no. 2, pp. 543-565

We exhibit an explicit algorithm to compute three-point branched covers of the complex projective line when the uniformizing triangle group is Euclidean.

Nous exposons un algorithme explicite pour calculer les revêtements ramifiés en trois points de la droite projective complexe lorsque le groupe de triangles uniformisant est euclidien.
