Archimedean local height differences on elliptic curves. (arXiv:1807.04153v1 [math.NT])

To compute generators for the Mordell-Weil group of an elliptic curve over a number field, one needs to bound the difference between the naive and the canonical height from above. We give an elementary and fast method to compute an upper bound for the local contribution to this difference at an archimedean place, which sometimes gives better results than previous algorithms. 查看全文>>
