SUMMARY:Karoubi-Grothendieck-Witt spectra - Fabian Hebestreit (University 
 of Aberdeen)

DESCRIPTION:jt with B.Calm&egrave\;s\, E.Dotto\, Y.Harpaz\, K.Moi\, M.Land
 \, D.Nardin\, T.Nikolaus and W.Steimle\nI 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-Grothendi
 eck-Witt-spectra of the title. It is this version of Grothendieck-Witt spe
 ctra that satisfy Zariski (even Nisnevich) descent\, and as part of the id
 entification of the appropriate version of L-spectra\, I will give a unifi
 cation 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.
