Title
Differential forms and bilinear forms under field extensions
Author
Abstract
Let F be a field of characteristic p > 0. Let Omega(n)(F) be the F-vector space of n-differentials of F over F-p. Let K = F(g) be the function field of an irreducible polynomial g in in m >= 1 variables over F. We derive an explicit description of the kernel of the restriction map Omega(n)(F) -> Omega(n)(K). As an application in the case p = 2, we determine the kernel of the restriction map when passing from the Witt ring (rasp. graded Witt ring) of symmetric bilinear forms over F to that over such a function field extension K.
