DESCRIPTION:The Landau-Ginzburg/Calabi-Yau (LG/CY) correspondence is a pro
 posed equivalence between two enumerative theories associated to a homogen
 eous polynomial: the Gromov-Witten theory of the hypersurface cut out by t
 he polynomial in projective space\, and the Landau-Ginzburg theory of the 
 polynomial when viewed as a singularity.  Such a correspondence was origin
 ally suggested by Witten in 1993 as part of a far-reaching conjecture rela
 ting the "gauged linear sigma models" arising at different phases of a GIT
  quotient.  I will discuss an explicit formulation and proof of Witten's p
 roposal for complete intersections in projective space\, generalizing the 
 LG/CY correspondence for hypersurfaces and introducing a number of new fea
 tures.  This represents joint work with Dustin Ross.
