Abstract
The stable classification of quadratic forms over a field is given by the Witt group. Topology, via surgery theory, has embedded the Witt groups in a general theory of forms over any ring with involution. In this paper we use geometrically inspired methods to make computations. General results on the L-theory of a Laurent polynomial extension are used to study the Witt groups of genus 0 function fields.
