First and second -groups of an elliptic curve over a global field of positive characteristic
arXiv:1711.05749
Abstract
In this paper, we show that the maximal divisible subgroup of groups and of an elliptic curve over a function field is uniquely divisible. Further those -groups modulo this uniquely divisible subgroup are explicitly computed. We also calculate the motivic cohomology groups of the minimal regular model of , which is an elliptic surface over a finite field.
