| Abstract: |
| In the computation of K- and L-groups of group rings, two basic infinite groups that one needs to consider are the infinite cyclic group and the infinite dihedral group. The computation of their K- and L-theories are classical results and can be stated, roughly, as follows: There is an excisive approximation from the left which is an equivalence up to an error "Nil" term; furthermore the Nil terms for the infinite cyclic and the the infinite dihedral groups are related, for suitable dualities (the Nil-Nil theorem). We give a generalization of these results to Grothendieck-Witt theory (and other related theories) in the setting of Poincaré categories. |
