DESCRIPTION:Speakers: Thorger Geiß (Universität Münster)\n\nAbstracth h
 omotopy theory seminar\nThe classical Freudenthal Suspension Theorem is th
 e statement that\, given a space X\, the connectivity of the unit map X ->
  ΩΣX of the loop-suspension adjunction is (roughly) twice the connectivi
 ty of X. In this talk\, I will discuss the setting of oriented (or directe
 d) homotopy theory\, in which spaces are replaced by higher\, i.e. (∞\,
 ω)-\, categories and the cartesian product by the Gray tensor product\, a
 nd generalize the Freudenthal Suspension Theorem in this context. This giv
 es\, in particular\, evidence for a yet-elusive "oriented topos theory".\n
