Title: A brief introduction to quadratic spaces
Abstract: The level of a field k is defined to be the minimum n such that has a solution over . It turns out that if , then for some . The proof is a beautiful application of Pfister forms.
On our way to prove this result, we will introduce basic concepts in algebraic quadratic form theory, including the pioneering work of Witt and Pfister.
