DESCRIPTION:Tom Gannon\, UCLA\n\n\nTitle: Quantization of the Ngô Morphism
 \n\n\nAbstract: We will discuss work\, joint with Victor Ginzburg\, on a q
 uantization (non-commutative deformation) of the Ngô morphism\, a morphis
 m of group schemes which plays a key role in Ngô’s proof of the fundame
 ntal lemma in the Langlands program. We will also discuss how the tools us
 ed to construct this morphism can be used to prove conjectures of Ben-Zvi
 —Gunningham\, which predict that this morphism gives “spectral decompo
 sition” of DG categories with an action of a reductive group over the co
 arse quotient of a maximal Cartan subalgebra by the affine Weyl group.We w
 ill discuss work\, joint with Victor Ginzburg\, on a quantization (non-com
 mutative deformation) of the Ngô morphism\, a morphism of group schemes w
 hich plays a key role in Ngô’s proof of the fundamental lemma in the La
 nglands program. We will also discuss how the tools used to construct this
  morphism can be used to prove conjectures of Ben-Zvi—Gunningham\, which
  predict that this morphism gives “spectral decomposition” of DG categ
 ories with an action of a reductive group over the coarse quotient of a ma
 ximal Cartan subalgebra by the affine Weyl group.
