This description may be intangible at first for us to sink our hands into but it turns out to be a great con crete technique that relates to many things we care about as algebraic geo meters! We will interpret it in this talk. I will explain in toric geometr y concretely what this means for us. Afterwards\, I will explain why it’ s yet another reason we should listen to our string theoretic friends. Nam ely\, I hope to have enough time to explain how it gives us applications i n mirror symmetry and derived categories. Exoflops are a recurring charact er in my joint work with David Favero (Alberta)\, Chuck Doran (Alberta)\, and Dan Kaplan (Birmingham).\n LOCATION:https://researchseminars.org/talk/notts_ag/31/ END:VEVENT END:VCALENDAR
