Kreiman-Lakshmibai-Magyar-Weyman Ideas
Speaker(s): Alex Weekes
Abstract: I'll discuss an ongoing project of mine with Dinakar Muthiah and Oded Yacobi, which is based on ideas of Kreiman-Lakshmibai-Magyar-Weyman.  It is aimed at developing a "nice" standard monomial theory for the affine Grassmannian in type A, where "nice" means hopefully close in spirit to Hodg... read more

PIRSA:16090061  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Shifted Yangians, loop groups, and (co)products
Speaker(s): Alex Weekes
Abstract: I'll describe a family of algebras called shifted Yangians, which arise as deformation quantizations of certain spaces related to loop groups.  I'll also describe coproducts for these algebras, which are related to multiplication in the loop group.  Physically, this fits into the s... read more

PIRSA:16010082  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Symplectic duality and a presentation of the cohomology of Nakajima quiver varieties
Speaker(s): Alex Weekes
Abstract: We will discuss a (conjectural) explicit presentation for the equivariant cohomology of Nakajima quiver varieties of type ADE.  This presentation arises as a shadow of the expected symplectic duality between slices to Schubert varieties in the affine Grassmannian and Nakajima quiver varieti... read more
