Alexandru BuiumDepartment of Mathematics and Statistics University of New Mexico Albuquerque NM 87131 USA
-jets of finite flat maps of schemes are generally neither finite nor flat. However, for -isogenies, and in particular for -divisible groups, this pathology tends to disappear «in the limit". We illustrate this in the case of , elliptic curves, and formal groups of finite height.
