Abstract

Let OK\mathcal{O}_K be a discrete valuation ring with fraction field KK of characteristic 00 and algebraically closed residue field kk of characteristic p>0p > 0. Let A/KA/K be an abelian variety of dimension gg with a KK-rational point of order pp. In this article, we are interested in the reduction properties that A/KA/K can have. After discussing the general case, we specialize to g=1g=1, and we study the possible Kodaira types that can occur.
