Title: Quantum critical cohomology
Abstract: This will be a report on joint work with Yalong Cao, Yehao Zhou, and Zijun Zhou. 

As a part of our recent work on critical stable envelopes, we are able to determine the quantum critical cohomology for symmetric quivers with potential. 

Moreover, a certain asymmetry of the framing of the quiver is allowed, making geometries like the Hilbert scheme of points in the affine 3-space an example of our general theory.
