On the Covariant Dieudonné-Module of an Abelian Variety of Dimension Two over W(k).
The purpose of this paper is to generalize, to certain commutative formal groups of dimension one and height greater than one defined over the ring of integers of a finite extension of , some results on -adic interpolation developed by Kubota, Leopoldt, Iwasawa, Mazur, Katz and others notably for the multiplicative group , and which they used to construct -adic -functions.
There are many similarities between elliptic curves and formal groups of finite height. The points of order of a generic formal group are studied in order to develop the formal group analogue (applied to points of order ) of the concept of level structure and that of the -pairing known in elliptic curve theory.
