The exis tence of THH in such diverse contexts motivated Ponto to introduce a notio n that can encompass the various perspectives: a shadow of bicategories. O n the other side\, many versions of THH have been generalized to the homot opy coherent setting providing us with motivation to develop an analogous homotopy coherent notion of shadows.\n\nThe goal of this talk is to use an appropriate bicategorical notion of THH to prove that a shadow on a bicat egory is equivalent to a functor out of THH of that bicategory. We then us e this result to give an alternative conceptual understanding of shadows a s well as an appropriate definition of a homotopy coherent shadow.\n\nThis is joint work with Kathryn Hess.\n LOCATION:https://researchseminars.org/talk/BilTop/36/ END:VEVENT END:VCALENDAR
