Description of course:
This course will provide an introduction to the algebraic theory of
quadratic forms over fields. Topics will include the elementary
invariants (discriminant and Hasse invariant), classification over
various fields (real numbers, rational numbers, p-adic numbers, finite
fields, and rational function fields), isotropy and the u-invariant,
the Witt group, and Pfister forms. Along the way, we will also cover
the basic theory of quaternion algebras. Special topics might include
local-global principals (e.g., Hasse-Minkowski), sums of squares
(e.g., Lagrange’s theorem and Pfister’s bound for the Pythagoras
number), Milnor K-theory, and orthogonal groups, depending on the
interests of the participants.
Expected background:
Some prior experience with linear algebra and Galois theory will be
necessary.
Grading:
Your grade will be based on class participation and a final project.
