Vidunas, R. and He, Y. ORCID: 0000-0002-0787-8380 (2018). Composite genus one Belyi maps. Indagationes Mathematicae, 29(3), pp. 916-947. doi: 10.1016/j.indag.2018.02.001


Motivated by a demand for explicit genus 1 Belyi maps from theoretical physics, we give an efficient method of explicitly computing genus one Belyi maps by (1) composing covering maps from elliptic curves to the Riemann sphere with simpler (univariate) genus zero Belyi maps, as well as by (2) composing further with isogenies between elliptic curves. The computed examples of genus 1 Belyi maps has doubly-periodic dessins d’enfant that are listed in the physics literature as so-called brane-tilings in the context of quiver gauge theories
