SUMMARY:The many mirrors of the Grassmannian (and beyond)
CLASS:PUBLIC
DESCRIPTION:SPEAKER:\n Elana Kalashnikov\n\nAFFILIATION:\n University of Wa
 terloo\n\nLOCATION:\n MC 5501\n\nABSTRACT: The mirror of a smooth Fano to
 ric variety is a Laurent\npolynomial\, and this Laurent polynomial encodes
  interesting\nenumerative data of the toric variety.  For example\, the J
 acobian\nring of the Laurent polynomial is isomorphic to the small quantum
 \ncohomology ring of the toric variety. In this talk\, I’ll describe\nth
 is aspect of the (now basically classical) toric mirror theorem\, and\nexp
 lain how this picture is expected to extend to other smooth Fano\nvarietie
 s. The Grassmannian’s strong combinatorial structure  makes\nit one of 
 the nicest examples of non-toric Fano varieties to study in\nthis context.
  I’ll present several mirror constructions for the\nGrassmannian that ea
 ch reflect a different perspective on its\ngeometry. Finally\, I’ll disc
 uss some extensions of these\nconstructions to generalizations of the Gras
 smannian.
