A minimal model for prestacks and morphisms of operadic algebras via Koszul duality for box operads
Lander Hermans
Prestacks are algebro-geometric objects whose defining relations are far from quadratic. Indeed, they are cubic and quartic, and moreover inhomogeneous. Similarly, a morphism of $P…

A Deligne conjecture for prestacks
Ricardo Campos, Lander Hermans
We prove an analog of the Deligne conjecture for prestacks. We show that given a prestack , its Gerstenhaber--Schack complex is nat…
