In functorial field theory language\, this means t hat the theory is twisted\, which gives rise to an anomaly theory. In this talk\, we give a detailed construction of this anomaly theory\, as a func tor that sends manifolds to infinite-dimensional Clifford algebras and bor disms to bimodules.\n LOCATION:https://researchseminars.org/talk/GoeTop/4/ END:VEVENT END:VCALENDAR
