摘要
There is a canonical A(n)-fibration from a (2n + 1)-dimensional smooth affine quadric Y-n to an (n+ 1)-dimensional punctured affine space X. For each rank r at least n, we construct a nontrivial algebraic vector bundle of rank r on X-n with trivial pullback to Y-n. Moreover, we construct continuous families of arbitrarily large dimensional pairwise non-isomorphic rank n bundles on X-n with trivial pullbacks to Y-n.
