ABSTRACT: D-critical schemes and Artin stacks were introduced by Joyce  
in 2015, and play a central role in Donaldson-Thomas theory. They  
typically occur as truncations of (-1)-shifted symplectic derived  
schemes, but the problem of constructing the d-critical structure on a  
“DT moduli space” without passing through derived geometry is wide  
open. We discuss this problem, and new results in this direction, when  
the moduli space is the Hilbert (or Quot) scheme of points on a  
Calabi-Yau 3-fold. Work in progress with Michail Savvas.

Andrea, Alessandro and Michele
