Witt groups of Grassmann varieties
Paul Balmer, Baptiste Calmès
We compute the total Witt groups of (split) Grassmann varieties, over any regular base X. The answer is a free module over the total Witt ring of X. We provide an explicit basis fo…

Geometric description of the connecting homomorphism for Witt groups
Paul Balmer, Baptiste Calmès
We give a geometric setup in which the connecting homomorphism in the localization long exact sequence for Witt groups decomposes as the pull-back to the exceptional fiber of a sui…

Push-forwards for Witt groups of schemes
Baptiste Calmès, Jens Hornbostel
We define push-forwards for Witt groups of schemes along proper morphisms, using Grothendieck duality theory. This article is an application of results of the authors on tensor-tri…
