The quaternionic Maass Spezialschar on split $SO (8)$

Jennifer Johnson-Leung, Finn McGlade, Isabella Negrini +2

The classical Maass Spezialschar is a Hecke-stable subspace of the space of holomorphic Siegel modular forms of genus two and level one cut out by certain linear relations among Fo…

Prime isogenous discriminant ideal twins

Alexander J. Barrios, Maila Brucal-Hallare, Alyson Deines +2

Let $E_{1}$ and $E_{2}$ be elliptic curves defined over a number field $K$ . We say that $E_{1}$ and $E_{2}$ are discriminant ideal twins if they are not $K$ -isomorphic and have the…

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…
