DESCRIPTION:Speaker : Arpon Raksit - MIT\n\nTitle : Canonical lifts and spe
 ctral algebraic geometry\n\nAbstract :Let X be an elliptic curve over a pe
 rfect field k of positive characteristic. Serre–Tate studied the deforma
 tion theory of such X\, and one of their discoveries was that when X is or
 dinary\, it admits a canonical lifting to the ring of Witt vectors W(k) (w
 ith some special features). In this talk\, I'll discuss a connection betwe
 en this phenomenon and properties of the moduli of elliptic curves in spec
 tral algebraic geometry introduced by Lurie.
