On the Visibility category of the Shafarevich--Tate group
Barinder S. Banwait, Jerson Caro, Shiva Chidambaram
Given an elliptic curve over $\Q$ and a nontrivial element of its Shafarevich--Tate group $\Sha(E)$, we introduce the \textbf{Visualization category} $\V(E; σ)$ of abelian…

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…

Examples of abelian surfaces failing the local-global principle for isogenies
Barinder S Banwait
We provide examples of abelian surfaces over number fields whose reductions at almost all good primes possess an isogeny of prime degree rational over the residue field,…
