Talk consists of two parts. In the first one I am going to discuss the role of Cohomological Hall algebras in the generalized AGT conjecture. It gives a 3-dimensional Calabi-Yau point of view on some results in geometric representation theory related to moduli spaces of instantons. The second part of the talk is devoted to some speculations related to 3- dimensional gauge theories. The speculations are devoted to Cohomological Hall algebras as well as generalized RiemannHilbert correspondence.
