WebConfocal quadrics capture (encode) and geometrize spectral properties of symmetric operators. WebA central method in the theory of quadratic forms is the study of function ﬁelds of projective quadrics. In particular, it is important to ask when there is a rational map from one quadric over a ﬁeld to another. This suggests the problem of determining when two quadrics are birational, which turns out to be much harder.

WebThe geometric approach is so called because in it the quadric surfaces are instead represented by points, vectors, and scalars that are specific to each type of surface. For example, spheres are represented by a centerpoint and radius. WebIntersection homology theory provides a way to obtain generalized Poincare duality, as well as a signature and characteristic classes, for singular spaces. For this to work, one has had to assume however that the space satisfies the so-called Witt condition. We extend this approach to constructing invariants to spaces more general than Witt spaces.
