Weak approximation for linear systems of quadrics
Abstract
Description
We give local conditions at the infinite places of a number field K ensuring that the intersection of n quadrics in projective N-space over K, N >> n, satisfies weak approximation.
There are substantial changes, of which the most important is a new inductive strategy giving a much better (quadratic instead of super-exponential) bound
