Abstract
In this paper we describe how to perform computations with Witt vectors of length 3 in an efficient way and give a formula that allows us to compute the third coordinate of the Greenberg transform of a polynomial directly. We apply these results to obtain information on the third coordinate of the j-invariant of the canonical lifting as a function on the j-invariant of the ordinary elliptic curve in characteristic p.
