Abstract

In their book Katz and Mazur discuss the moduli problem of the subgroup-schemes of elliptic curves. We give the classification of the finite subgroups of the Tate curve before. Moreover, Katz and Mazur define the universal finite subgroup of an elliptic curve. In this paper we give an explicit construction of the universal finite subgroup of the Tate curve via isogenies and the stringy power operation of Tate K-theory.
