Increasing the Size of Tame Shafarevich Groups

Andreea Iorga, Ravi Ramakrishna

Let $K$ be a number field with $S$ a finite set of primes. We study the cohomology of $F_{p} [G_{K, S}]$ -modules $A$ , in particular the Shafarevich groups $\Sha^i_S(K,A)$ for…

Towards a classification of $p^{2}$ -discriminant ideal twins over number fields

Alyson Deines, Asimina S. Hamakiotes, Andreea Iorga +3

Isogenous elliptic curves have the same conductor but not necessarily the same minimal discriminant ideal. In this article, we explicitly classify all $p^{2}$ -isogenous elliptic curv…
