Higher Koszul duality and -affineness

James Pascaleff, Emanuele Pavia, Nicolò Sibilla

In this paper we study -Koszul duality in the topological setting, and the closely related question of \emph{-affineness} for Betti stacks. The -Kosz…

Equivariant Elliptic Cohomology and Mapping Stacks

Nicolò Sibilla, Paolo Tomasini

We introduce a new cohomology theory for stacks called elliptic Hochschild homology, prove some fundamental properties and compute it in some classes of examples. We then introduce…

An Orlov theorem for matrix factorizations with multiple factors

Alessandro Lehmann, Nicolò Sibilla

We prove a generalization of Orlov's theorem for matrix factorizations with steps. Let be a regular scheme, a flat morphism and i…

Hochschild-Kostant-Rosenberg isomorphism for derived Deligne-Mumford stacks

Lie Fu, Mauro Porta, Sarah Scherotzke +1

We prove a Hochschild--Konstant--Rosenberg (HKR) theorem for arbitrary derived Deligne--Mumford (DM) stacks, extending the results of Arinkin-Căldăraru-Hablicsek in the smooth, g…

Fourier--Mukai equivalences for formal groups and elliptic Hochschild homology

Sarah Scherotzke, Nicolò Sibilla, Paolo Tomasini

This paper establishes a unifying framework for various forms of twisted Hochschild homology by comparing two definitions of elliptic Hochschild homology: one introduced by Moulino…

Speculations on higher Fukaya categories

James Pascaleff, Nicolò Sibilla

We investigate a possible theory of higher Fukaya categories associated to -shifted symplectic stacks, where . We consider two paradigmatic cases, the shifted cotangen…
