EQUIVARIANT STIEFEL-WHITNEY CLASSES

[摘要] We develop a theory of equivariant Stiefel-Whitney classes for equivariant orthogonal vector bundles over schemes, parallel to Grothendieck's theory of equivariant Chern classes for equivariant linear vector bundles. We apply it to generalise earlier results on characteristic classes of 'trace forms', due to Serre, Frohlich, Snaith, Jardine, Esnault, Viehweg and the author.
