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. WebSci-Hub Geometry of Quadrics and Spectral Theory.
