Abstract

We construct an algorithm for solving the following problem: given a number field K, a positive integer N, and a positive real number B, determine all points in \mathbb PN(K) having relative height at most B. A theoretical analysis of the efficiency of the algorithm is provided, as well as sample computations showing how the algorithm performs in practice. Two variants of the method are described, and examples are given to compare their running times. In the case N=1 we compare our method to an earlier algorithm for enumerating elements of bounded height in number fields.
