Symplectic complex bundles over real algebraic four-folds
Published online by Cambridge University Press: 09 April 2009
Abstract
Let X be a compact affine real algebraic variety of dimension 4. We compute the Witt group of symplectic bilinear forms over the ring of regular functions from X to C. The Witt group is expressed in terms of some subgroups of the cohomology groups .
