Abstract

We characterize the possible reductions of jj-invariants of elliptic curves which admit complex multiplication by an order O\mathcal{O} where the curve itself is defined over Zp\mathbb{Z}_p. In particular, we show that the distribution of these jj-invariants depends on which primes divide the discriminant and conductor of the order.
