Twisted K-theory, Real $A$ -bundles and Grothendieck-Witt groups

Max Karoubi, Charles Weibel

We introduce a general framework to unify several variants of twisted topological $K$ -theory. We focus on the role of finite dimensional real simple algebras with a product-preserv…

Relative Cartier Divisors and Laurent Polynomial Extensions

Vivek Sadhu, Charles Weibel

If $i : A \subset B$ is a commutative ring extension, we show that the group $I (A, B)$ of invertible $A$ -submodules of $B$ is contracted in the sense of Bass, with $L\mathcal…

Principal ideals in mod- $ℓ$ Milnor $K$ -theory

Charles Weibel, Inna Zakharevich

Fix a symbol $a$ in the mod- $ℓ$ Milnor $K$ -theory of a field $k$ , and a norm variety $X$ for $a$ . We show that the ideal generated by $a$ is…

The Witt group of real algebraic varieties

Max Karoubi, Marco Schlichting, Charles Weibel

Let $V$ be an algebraic variety over $R$ . The purpose of this paper is to compare its algebraic Witt group $W (V)$ with a new topological invariant $W R (V_{C})$ , base…
