AbstractLet K be a number field, and let
$$X \subseteq \mathbb{P}_K^{s - 1} $$
be asmooth complete intersection defined over K. In this paper, weakapproximation is shown to hold for X provided s exceeds some functionof the degree and codimension of X. This is a corollary of a moregeneral result about the number of integral points on certain affine varieties in homogeneously expanding regions. This general result isestablished via a suitable adaptation of the Hardy-Littlewood Circle Method.
