DESCRIPTION:Title: <a href="https://researchseminars.org/talk/JENTE/61/">P
 rimes of cyclic reduction for elliptic curves</a>\nby Francesco Campagna (
 University of Copenhagen/MPIM Bonn) as part of Japan Europe Number Theory 
 Exchange Seminar\n\n\nAbstract\nGiven an elliptic curve E over a number fi
 eld F and a prime of good reduction p\, the group of rational points on th
 e reduced curve E mod p is abelian on at most two generators. If one gener
 ator suffices\, we call p a prime of cyclic reduction for E. In this talk 
 I will explain why the set of primes of cyclic reduction for E should have
  a natural density and I will discuss the possible vanishing of this densi
 ty. This is a joint work with Peter Stevenhagen.\n
