Abstract
I explain the cluster positivity conjecture of Fomin-Zelevinsky (now a theorem of Schiffler and Lee) and its quantum version due to Berenstein-Zelevinsky. I show, following Nagao and Efinov, how a cohomological version of Donaldson-Thomas theory enters this quantum picture. I finally explain how a purity result proves a special, and possibly the general, case of the quantum cluster positivity conjecture (joint work with Davison, Maulik, Schuermann).
