Abstract
The paper is devoted to several questions related to the notion of Cohomological Hall algebra (COHA for short) introduced few years ago by Maxim Kontsevich and the author. In particular we discuss a class of representations of COHA in the cohomology groups of the moduli spaces of stable framed objects. We speculate about possible sources of interesting representations as well as about some applications to geometry and physics.
