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 $X$ be a a $(- 1)$ -shifted symplectic derived Deligne--Mumford stack. Thanks to the Darboux lemma of Brav--Bussi--Joyce, $X$ is lo…

Gluing invariants of Donaldson--Thomas type -- Part I: the Darboux stack

Benjamin Hennion, Julian Holstein, Marco Robalo

Let $X$ be a (-1)-shifted symplectic derived Deligne--Mumford stack. In this paper we introduce the Darboux stack of $X$ , parametrizing local presentations of $X$ as a derived crit…

Choices of HKR isomorphisms

Marco Robalo

In this short note we record the fact that the set of multiplicative HKR natural equivalences defined simultaneously for all derived schemes, functorialy splitting the HKR-filtrati…

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…
