DESCRIPTION:Speakers: Hiraku Nakajima (Tokyo/Kashiwa)\n\nBow varieties\, i
 ntroduced by Cherkis\, include affine type A quiver varieties\, affine Gra
 ssmannian slices\, and nilpotent orbits closures as special cases. They in
 herit properties from three ancestors\, hence give geometric realizations 
 of representations of affine Yangians\, affine Lie algebras and Weyl group
 s. They have three types of involutions\, whose fixed point sets include q
 uiver varieties\, affine Grassmannian slices\, nilpotent orbits\, now for 
 classical groups. (The latter two types of involutions were studied by de 
 Campos Affonso and Finkelberg-Hanany together with myself respectively.) T
 hen I will speculate geometric realizations of various algebras.\n\nhttps:
