In the first part of the talk, we introduce the Cohomological Hall algebra (CoHa) of the m-loop quiver and modules over it which arise via framed stable objects. We show that these modules are cyclic and give a presentation.
We generalize these results to modules over the semi-stable CoHa of an arbitrary quiver (with trivial potential) in part two. If time permits we discuss the Harder-Narasimhan methods involved in the proof and further applications of these.
