How Twist Class Redundancy Drives the Prediction of Traces of Frobenius of Elliptic Curves
Angelica Babei, Ujjawal Shah, Malick Kebe
Recent interest in applying machine learning methods to predict invariants of mathematical objects has yielded models with surprisingly strong performance, including those predicti…

The moduli space of representations of the modular group into
Angelica Babei, Andrew Fiori, Cameron Franc
In this paper we construct a large four-dimensional family of representations of the modular group into . Precisely, this family is an etale cover of degree of an open su…

Families of -congruence subgroups of the modular group
Angelica Babei, Andrew Fiori, Cameron Franc
We introduce and study families of finite index subgroups of the modular group that generalize the congruence subgroups. Such groups, termed -congruence subgroups, are obtained…
