NICK ROZENBLYUM THESIS

Beilinson’s talk is intended to be a kind of introduction to those by Rozenblyum. Models for spaces of rational maps Abstract I will discuss the equivalence between three different models for spaces of rational maps in algebraic geometry. This immediately implies the statement for any finite extension of K. I will explain its construction and basic properties. A key player in the story is the deRham stack, introduced by Simpson in the context of nonabelian Hodge theory. I will also explain how this approach compares to more familiar definitions. No previous knowledge of the above subjects is needed.

October 4 Thursday and October 8 Monday. I will begin with an overview of Grothendieck-Serre duality in derived algebraic geometry via the formalism of ind-coherent sheaves. Wed, 7 Nov D-modules in infinite type. Other Contributors Massachusetts Institute of Technology.

The latter will be devoted to a new approach to the foundations of D-module theory developed by Gaitsgory and Rozenblyum. It is a convenient formulation of Gorthendieck’s theory of crystals in characteristic 0.

Models for spaces of rational maps. The scientific name for this is “Weil restriction of scalars”. Already in Lusztig proposed a very elegant, but still conjectural, geometric construction of twisted parabolic induction for unramified maximal tori in arbitrary reductive p-adic groups. October 4 Thursday rpzenblyum October 8 Monday. Thu, 8 Nov This implies the statement in the more general setting considered at the seminar when the target variety is connected and locally isomorphic to an affine space.

In particular, I will explain the relation between spaces of quasi-maps and the model for the space of rational maps which Gaitsgory uses in his recent contractibility theorem. Department Massachusetts Institute of Technology.

Motives and derived algebraic geometry – Essen, May

This gives a description of flat connections on a quasi-coherent sheaf on Bung which is local on the Ran space. Abstract For an algebraic group G and a projective curve X, we study the category of D-modules on the moduli space Bung of principal G-bundles on X using ideas from conformal field theory.

Gaitsgory formulating the theory of D-modules using derived algebraic geometry. Thu, 4 Oct This construction has a number of benefits; for instance, Kashiwara’s Lemma and h-descent are easy consequences of the definition. Thu, 18 Oct D-modules in infinite type.

One uses here the following fact: Collections Mathematics – Ph. Sun, 30 Sep Mon, 22 Oct This immediately implies the statement for any finite extension of K.

Motives and derived algebraic geometry

Thu, 11 Oct I will describe the known examples of this phenomenon and their relationship to the local Langlands correspondence. Duality and D-modules via derived algebraic geometry.

We describe this category in terms of the action of infinitesimal Hecke functors on the category of quasi-coherent sheaves on Bung. Mon, 29 Oct Nick will continue next Thursday: Part of the talk will be based on joint work with Jared Weinstein Boston University.

I will explain how each of the different models for these spaces exhibit different properties of their categories of D-modules.

Terms of use M. This family of functors, parametrized by the Ran space of X, acts by averaging a quasi-coherent sheaf over infinitesimal modifications of G-bundles at prescribed yhesis of X.
