I then describe my recent generalization of these results in which algebras are replaced by monoidal (higher) categories. Prerequisites: some familiarity with the bicategory of algebras and bimodules\, as explained for instance in the talk by Robert Paré.​\n\nContact Information: Ellen Lynch LOCATION:Join Zoom Meeting https://us02web.zoom.us/j/81872756284?pwd=VGVQcW8vRmFXK1hvTk5UZURGSXg5UT09 Join our Cloud HD Video Meeting Zoom is the leader in modern enterprise video communications\, with an easy\, reliable cloud platform for video and audio conferenci URL:https://www.dal.ca/news/events/2020/10/13/_cat_seminar.html UID:https://www.dal.ca/news/events/2020/10/13/_cat_seminar/_jcr_content/contentPar/dcalfacultyevent.html END:VEVENT END:VCALENDAR
