Derived Enhancements of $T$ -fixed subschemes

Marc Besson, Shiyixin Liang

For $X$ a conical affine symplectic singularity with $T = T \times G_{m}$ -action, the fixed scheme $X^{T}$ and the map $X^{T} \to X$ carry much information about…

A Coherent Version of Geometric Satake Equivalence for Type A

Shiyixin Liang

In this paper we prove a coherent version of geometric Satake equivalence proposed in Cautis-Williams' work arXiv:2306.03023 for type A. In their work, they studied an abelian vers…
