Supersingular curves with small noninteger endomorphisms
Supersingular curves with small noninteger endomorphisms
We introduce a special class of supersingular curves over ކ p 2 , characterized by the existence of noninteger endomorphisms of small degree.We prove a number of properties about this set.Most notably, we can partition this set into subsets such that curves within each subset have small-degree isogenies between them, …
