Welcome to the official home-page of the project Info-Mod.

The aim of the project is to understand, at least for now, subgroups of the modular group that are generated by one element, i.e. one parameter subgroups.

To achieve this goal we develop a sofware (called Info-Mod) together with a web application (called Sunburst).

The mathematical background of the subject is available in following two articles:

Binary Quadratic Forms as Dessins, (with M. Uludag, A. Zeytin and M. Durmus)


On the Reduction Theory of Binary Quadratic Forms, by A.Zeytin

Both are available at:
