The Mathieu group is a Galois group over

Xiaoyu Huang, Blake Jackson, Kyu-Hwan Lee +3

Researchers studying the inverse Galois problem realized 25 of the 26 sporadic finite simple groups as Galois groups over during 1984-1989. We complete this program by…

Decision trees, Frobenius traces, and Weierstrass coefficients of elliptic curves

Barinder S. Banwait, Xiaoyu Huang, Kyu-Hwan Lee +3

We investigate the extent to which the coefficients of the reduced minimal Weierstrass model of an elliptic curve are determined by the Diric…

On the Identification of Elliptic Curves That Admit Infinitely Many Twists Satisfying the Birch-Swinnerton-Dyer Conjecture

Barinder S. Banwait, Xiaoyu Huang

Recent work of Burungale-Skinner-Tian-Wan established the first infinite families of quadratic twists of non-CM elliptic curves over for which the strong Birch-Swinner…

Learning Euler Factors of Elliptic Curves

Angelica Babei, François Charton, Edgar Costa +5

We apply transformer models and feedforward neural networks to predict Frobenius traces from elliptic curves given other traces . We train further models to predict $a_p…

Machine Learning Approaches to the Shafarevich-Tate Group of Elliptic Curves

Angelica Babei, Barinder S. Banwait, AJ Fong +2

We train machine learning models to predict the order of the Shafarevich-Tate group of an elliptic curve over . Building on earlier work of He, Lee, and Oliver, we show…
