In the present talk, I will broadly introduce two-dimensional cohomological Hall algebras of curves and surfaces, and discuss their categorification. In the second part of the talk, I will discuss in detail an ongoing joint work with Diaconescu, Schiffmann, and Vasserot, in which we consider the cohomological Hall algebra of a Kleinian surface singularity.
