Algebraic Knots and their Universal K^MW_2-Coverings
Matthias Wendt, Thor Wittich
Over suitable base fields of characteristic not , including algebraically closed ones, we construct universal abelian -co…
Chow-Witt rings and topology of flag varieties
Thomas Hudson, Ákos K. Matszangosz, Matthias Wendt
The paper computes the Witt-sheaf cohomology rings of partial flag varieties in type A in terms of the Pontryagin classes of the subquotient bundles. The proof is based on a Leray-…
-connected components of classifying spaces and purity for torsors
Elden Elmanto, Girish Kulkarni, Matthias Wendt
In this paper, we study the Nisnevich sheafification of the presheaf associating to a smooth scheme the set of isomorphism classes of -torsors, f…
The real cycle class map
Jens Hornbostel, Matthias Wendt, Heng Xie +1
The classical cycle class map for a smooth complex variety sends cycles in the Chow ring to cycles in the singular cohomology ring. We study two cycle class maps for smooth real va…
On motivic obstructions to Witt cancellation for quadratic forms over schemes
Matthias Wendt
The paper provides computations of the first non-vanishing -homotopy sheaves of the orthogonal Stiefel varieties which are relevant for the unstable isometry classifi…
Oriented Schubert calculus in Chow-Witt rings of Grassmannians
Matthias Wendt
We apply the previous calculations of Chow-Witt rings of Grassmannians to develop an oriented analogue of the classical Schubert calculus. As a result, we get complete diagrammatic…
