Foundations of Motivic Real K-Theory

Quadratic forms are ubiquitous throughout mathematics, playing a fundamental role in areas from arithmetic through algebra and geometry. In surgery theory, quadratic forms feature prominently in the classification of smooth manifolds in a given homotopy type, while in arithmetic geometry they can be used to encode Galois and motivic cohomology classes via Milnor's conjecture. The theory of quadratic forms is naturally very sensitive to the prime 2. While in surgery theory this effect is critical, in algebraic geometry it was often set aside by assuming 2 to be invertible in all ground rings. A recent joint work of the PI and collaborators on the foundations of Hermitian K-theory uses…
