| Abstract: | We define push-forwards along projective morphisms in the Witt theory of smooth quasi-projective varieties over a field. We prove that they have standard properties such as functoriality, compatibility with pull-backs and projection formulas. |
| Keywords: | Witt theory of algebraic varieties Projective morphism Push-forward Gysin operator Thom isomorphism Deformation to the normal bundle |
