摘要
Negut formulated and proved an parabolic AGT correspondence, namely, certain q-deformed W-algebra acts on the equivariant K-theory of the moduli space of parabolic sheaves on P^1\times P^1 (a.k.a. affine Laumon space). The cohomological version remains open. In this talk I will outline a proof of the cohomological version of parabolic AGT in the rectangular case. A key ingredient in the proof is the critical stable envelope developed in my recent joint work with Yalong Cao, Andrei Okounkov, and Zijun Zhou.
