Abstract: | We introduce twisted Thom operators and the deformation to the normal cone isomorphisms in the derived Witt theory. Using these ingredients, we define push-forward maps of Witt groups along closed embeddings of smooth varieties and prove their standard properties, the most delicate of which turns out to be the functoriality of such maps. |
