Towards a classification of -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 -isogenous elliptic curv…

Prime isogenous discriminant ideal twins
Alexander J. Barrios, Maila Brucal-Hallare, Alyson Deines +2
Let and be elliptic curves defined over a number field . We say that and are discriminant ideal twins if they are not -isomorphic and have the…

The quaternionic Maass Spezialschar on split
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…
