Gluing invariants of Donaldson--Thomas type -- Part II: Matrix factorizations
Benjamin Hennion, Julian Holstein, Marco Robalo
This paper is a follow-up to arXiv:2407.08471. Let be a a -shifted symplectic derived Deligne--Mumford stack. Thanks to the Darboux lemma of Brav--Bussi--Joyce, is lo…

Gluing invariants of Donaldson--Thomas type -- Part I: the Darboux stack
Benjamin Hennion, Julian Holstein, Marco Robalo
Let be a (-1)-shifted symplectic derived Deligne--Mumford stack. In this paper we introduce the Darboux stack of , parametrizing local presentations of as a derived crit…

Gromov-Witten theory with derived algebraic geometry
Etienne Mann, Marco Robalo
In this survey we add two new results that are not in our paper [MR15]. Using the idea of brane actions discovered by Toen, we construct a lax associative action of the operad of s…
