Equivariant real cycle class map and Witt-sheaf cohomology of classifying spaces
Lorenzo Mantovani, Ãkos K. Matszangosz, Matthias Wendt
In this paper, we study equivariant real cycle class maps for group actions on real schemes, with a view toward Witt-sheaf characteristic classes. The cycle class maps take values…

Chow-Witt rings and topology of flag varieties
Thomas Hudson, Ãkos 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-…
