Orders of CM elliptic curves modulo p with at most two primes
Orders of CM elliptic curves modulo p with at most two primes
In this paper of 1988 N. Koblitz conjectured that given an elliptic curve E over the rationals, the order of the group of F p points of its reduction modulo p, |E(F p )|, is a prime number for infinitely many primes p.Since then a wide number of research articles …
