摘要:
We present an algorithm for computing an upper bound for the difference of the logarithmic height and the canonical height on elliptic curves. Moreover, a new method for performing the infinite descent on elliptic curves is given, using ideas from the geometry of numbers. These algorithms are practical and are demonstrated by a few examples.
