Hi all,
Our last NT seminar of the quarter is today at 11am. Our speaker is Lori Watson from Trinity College and she will be speaking on "Towards a classification of discriminant ideal twins over number fields" (abstract below). As usual we will go to lunch with the speaker after the talk.
Abstract:
Isogenous elliptic curves defined over a number field have the same conductor; however, their minimal discriminant ideals may differ. When two (cyclic) isogenous elliptic curves also have the same minimal discriminant ideal we say that they are discriminant ideal twins. In this talk, we discuss the ongoing classification of discriminant ideal twins.Towards a classification of discriminant ideal twins over number fields
