| Mar 3, 2023 at 16:22 | comment | added | Estwald | @DavidBen-Zvi Thank you David. I also want to know if W-algebra, which is an important part of the geometric Langlands program, can be described using this Tate version BRST reduction. I understand the usual construction of W-algebra by quantized Drinfeld--Sokolov reduction, but it seems that most author doesn't use this chiral algebra way by Beilinson, Drinfeld... Instead, they write down an explicit formula without caring too much about the topology. | |

I would also recommend the series of papers of Braunling-Groechenig-Wolfson. | |
