DESCRIPTION:Title: <a href="https://researchseminars.org/talk/AG-Davis/34/
 ">Two-dimensional cohomological Hall algebras of curves and surfaces\, and
  their categorification</a>\nby Francesco Sala (University of Pisa) as par
 t of UC Davis algebraic geometry seminar\n\n\nAbstract\nIn the present tal
 k\, I will broadly introduce two-dimensional cohomological Hall algebras o
 f curves and surfaces\, and discuss their categorification. In the second 
 part of the talk\, I will discuss in detail an ongoing joint work with Dia
 conescu\, Schiffmann\, and Vasserot\, in which we consider the cohomologic
 al Hall algebra of a Kleinian surface singularity.\n
