Categorification of the localized intersection product and Bloch conductor formula

Dario Beraldo, Massimo Pippi

We categorify the localized intersection product on arithmetic schemes defined by Kato--Saito in \cite{katosaito04}. As an application, we prove a generalization of Bloch conductor…

Coherent sheaves, sheared D-modules, and Hochschild cochains

Dario Beraldo, Kevin Lin, Wyatt Reeves

We show that the category of ind-coherent sheaves on a quasi-smooth scheme is naturally tensored over the category of sheared D-modules on its shifted cotangent bundle, commuting w…

Proof of the Deligne-Milnor conjecture

Dario Beraldo, Massimo Pippi

We apply methods of derived and non-commutative algebraic geometry to understand ramification phenomena on arithmetic schemes. As an application, we prove the Deligne-Milnor conjec…

Proof of the geometric Langlands conjecture IV: ambidexterity

D. Arinkin, D. Beraldo, L. Chen +5

This paper performs the following steps toward the proof of GLC in the de Rham setting: (i) We deduce GLC for G=GL_n; (ii) We prove that the Langlands functor L_G constructed in [G…

Proof of the geometric Langlands conjecture II: Kac-Moody localization and the FLE

D. Arinkin, D. Beraldo, J. Campbell +6

This paper is the second in a series of five that together prove the geometric Langlands conjecture. Our goals are two-fold: (1) Formulate and prove the Fundamental Local Equivalen…

Non-commutative nature of -adic vanishing cycles

Dario Beraldo, Massimo Pippi

Let be a flat, proper and regular scheme over a strictly henselian discrete valuation ring. We prove that the singularity category of the special fiber with its…

Non-commutative intersection theory and unipotent Deligne-Milnor formula

Dario Beraldo, Massimo Pippi

We apply methods of derived and non-commutative algebraic geometry to understand intersection theoretic phenomena on arithmetic schemes. Specifically, we categorify Bloch's interse…

Tempered D-modules and Borel-Moore homology vanishing

Dario Beraldo

We characterize the tempered part of the automorphic Langlands category D-mod(Bun_G) using the geometry of the big cell in the affine Grassmannian. We deduce that, for non-abel…

The spectral gluing theorem revisited

Dario Beraldo

We strengthen the gluing theorem occurring on the spectral side of the geometric Langlands conjecture. While the latter embeds into a category glued out of 'Fourie…

Sheaves of categories with local actions of Hochschild cochains

Dario Beraldo

The notion of Hochschild cochains induces an assignment from , affine DG schemes, to monoidal DG categories. We show that this assignment extends, under some appropriate finit…

The center of the categorified ring of differential operators

Dario Beraldo

Let \Y be a derived algebraic stack satisfying some mild conditions. The purpose of this paper is three-fold. First, we introduce and study H(\Y), a monoidal DG category that might…

On the extended Whittaker category

Dario Beraldo

Let be a connected reductive group, with connected center, and a smooth complete curve, both defined over an algebraically closed field of characteristic zero. Let $\operat…
