jt with B.Calmès, E.Dotto, Y.Harpaz, K.Moi, M.Land, D.Nardin, T.Nikolaus and W.Steimle I will explain an analogue of the fundamental fibre sequence relating connective K-, Grothendieck-Witt- and L-spectra that involves non-connective K-theory and the Karoubi-Grothendieck-Witt-spectra of the title. It is this version of Grothendieck-Witt spectra that satisfy Zariski (even Nisnevich) descent, and as part of the identification of the appropriate version of L-spectra, I will give a unification of the Bass-Heller-Swan and Shaneson splittings in K- and L-theory, respectively, that also allows for the computation of Grothendieck-Witt groups of Laurent polynomial rings.
