The Farey framework for SL2-tilings

thumbnail: Two paths in the Farey graph, corresponding to a certain SL₂-tiling thumbnail: Farey graph, Ford circles, and the truncated Farey graph thumbnail: Farey surface of a certain wild SL₂-tiling thumbnail: Farey complexes over integers mod 5, 6, 7

This website is devoted to the project on using a combinatorial approach to explore the connections between number theory and geometry that arise around Conway–Coxeter friezes and SL2-tilings over integer numbers and other rings, carried out at the Open University, UK.
