Microlocal sheaves on certain affine Springer fibers
Zhiwei Yun
3:00pm|Simonyi Hall 101 and Remote Access

For homogeneous affine Springer fibers (those with $G_m$ symmetry), we realize them as Lagrangian cycles inside ambient symplectic varieties, and make sense of microlocal sheaves supported on these affine Springer fibers. We also propose a...
