This homomorphism sends generators of the Bernstein's commutative subalgebra inside the affine Hecke algebra to Jucys-Murphy elements in the finite Hecke algebra. Construction employs the general strategy devised by Bezrukavnikov to prove the equivalence of coherent and constructible variants of the affine Hecke category. Namely, we identify an action of the category Rep(GL,) on the finite Hecke category, and lift this action to a functor from the perfect derived category of the Steinberg variety, by equipping it with various additional data.

  • Fundamental Local Equivalences in Quantum Geometric Langlands
    FUNDAMENTAL LOCAL EQUIVALENCES IN QUANTUM GEOMETRIC LANGLANDS JUSTIN CAMPBELL, GURBIR DHILLON, AND SAM RASKIN Abstract. In quantum geometric Langlands, the Satake equivalence plays a less prominent role than in the classical theory. Gaitsgory{Lurie proposed a conjectural substitute, later termed the fundamental local equivalence. With a few exceptions, we prove this conjecture and its extension to the affine flag variety by using what amount to Soergel module techniques. Contents 1. Introduction 1 2. Preliminary material 6 3. Fundamental local equivalences 10 Appendix A. Proof in the general case 27 References 29 1. Introduction 1.1. In the early days of the geometric Langlands program, experts observed that the fundamental objects of study deform over the space of levels κ for the reductive group G. For example, if G is simple, this is a 1-dimensional space. Moreover, levels admit duality as well: a level κ for G gives rise to a dual level1 κˇ for the Langlands dual group Gˇ. This observation suggested the existence of a quantum geometric Langlands program, deforming the usual Langlands program. The first triumph of this idea appeared in the work of Feigin{Frenkel [FF91], where they proved duality of affine W-algebras: WG,κ ' WG;ˇ κˇ. We emphasize that this result is quantum in its nature: the level κ appears. For the critical level κ = κc, which corresponds to classical geometric Langlands, Beilinson{Drinfeld [BDdf] used Feigin{Frenkel duality to give a beautiful construction of Hecke eigensheaves for certain irreducible local systems. 1.2. The major deficiency of the quantum geometric Langlands was understood immediately: the Satake equivalence is more degenerate.

  • HODGE THEORY and UNITARY REPRESENTATIONS of REDUCTIVE LIE GROUPS 3 Most Important
    AMS/IP Studies in Advanced Mathematics Hodge theory and unitary representations of reductive Lie groups Wilfried Schmid and Kari Vilonen Abstract. We present an application of Hodge theory towards the study of irreducible unitary representations of reductive Lie groups. We describe a conjecture about such representations and discuss some progress towards its proof. 1. Introduction In this paper we state a conjecture on the unitary dual of reductive Lie groups and formulate certain foundational results towards it. We are currently working towards a proof. The conjecture does not give an explicit description of the uni- tary dual. Rather, it provides a strong functorial framework for studying unitary representations. Our main tool is M. Saito’s theory of mixed Hodge modules [19], applied to the Beilinson-Bernstein realization of Harish Chandra modules [4] Our paper represents an elaboration of the first named author’s lecture at the Sanya Inauguration conference. Like that lecture, it aims to provide an expository account of the present state of our work. We consider a linear reductive Lie group GR with maximal compact subgroup KR. The complexification G of GR contains a unique compact real form UR such that KR = GR ∩ UR. We denote the Lie algebras of GR, UR, KR by the subscripted Gothic letters gR, uR, and kR ; the first two of these lie as real forms in g, the Lie algebra of the complex group G, and similarly kR is a realform of k, the Lie algebra of arXiv:1206.5547v1 [math.RT] 24 Jun 2012 the complexification K of the group KR.

  • Hodge Theory and Unitary Representations, in the Example of Sl(2, R)
    HODGE THEORY AND UNITARY REPRESENTATIONS, IN THE EXAMPLE OF SL(2, R). WILFRIED SCHMID AND KARI VILONEN Dedicated to David Vogan, on the occasion of his sixtieth birthday In our paper [4] we formulated a conjecture on unitary representations of reduc- tive Lie groups. We are currently working towards a proof; the technical difficulties are formidable. It has been suggested that an explicit description in the case of SL(2, R) would be helpful. The unitary representations of SL(2, R) have been worked out in great detail, of course, but even in this special case our construction of the inner product in terms of the D-module realization is not obvious. We begin with a quick summary of our conjecture in the general case of a re- ductive, linear, connected Lie group GR, with maximal compact subgroup KR. We let G and K denote the complexifications. The complex group G contains a unique compact real form UR such that UR ∩ GR = KR. Then UR acts transitively on the flag variety X of G, and K acts with finitely many orbits. The points of X corres- pond to Borel subalgebras b of the Lie algebra g of G. The quotients h = b/[b, b] constitute the fibers of a flat vector bundle. Since X is simply connected, we can think of h as a fixed vector space. This is the “universal Cartan”, and is acted on by the “universal Weyl group” W . Its dual h∗ contains the “universal root system” Φ and the system of positive roots Φ+, chosen so that [b, b] becomes the direct sum of the negative root spaces; h∗ also contains the “universal weight lattice” Λ.

    REPRESENTATION THEORY XVI Dubrovnik, Croatia, June 24-29, 2019 Organizers: DraˇzenAdamovi´c,Andrej Dujella, Hrvoje Kraljevi´c,Antun Milas, Pavle Pandˇzi´c,Mirko Primc, David Vogan ABSTRACTS OF TALKS 2 Real Groups Section Hodge Theory and Unitary Representations Jeffrey Adams, University of Maryland Irreducible representations of a reductive group carry a canonical Hodge filtration. Wilfried Schmid and Kari Vilonen have a precise conjecture relating this filtration to the signature of the canonical form on the representation which arises in the study of the unitary dual. We prove a weak form of their conjecture: roughly speaking the c-form is the reduction of the Hodge filtration modulo 2. This is joint work with Peter Trapa and David Vogan. Quantum Langlands duality of representations of W-algebras Tomoyuki Arakawa, RIMS, Kyoto We prove duality isomorphisms of certain representations of W-algebras which play an essential role in the quantum geometric Langlands Program and some related results. This is a joint work with Edward Frenkel. Dirac cohomology for complex classical groups Dan Barbasch, Cornell University In joint work with Daniel Wong and Chao-Ping Dong, we have classified the portion of the unitary dual with nontrivial Dirac cohomology. The results generalize the classification of unitary representations with nontrivial (g;K)−cohomology, and rely on earlier results joint with Pandˇzi´c. Arakawa-Suzuki functors for Whittaker modules Adam Brown, IST Austria The Milicic-Soergel category of Whittaker modules is a category of Lie algebra representations which generalize other well-known categories, such as the Bernstein-Gelfand-Gelfand category O. In this talk (inspired by the work of Arakawa and Suzuki for category O) we will construct a family of exact functors from the category of Whittaker modules to the category of finite-dimensional graded affine Hecke algebra modules, for type An.

  • A Perverse Sheaf Approach Toward a Cohomology Theory for String Theory
    A Perverse Sheaf Approach Toward a Cohomology Theory for String Theory 1 Abdul Rah. m¯an Department of Physics and Astronomy Howard University Washington, DC 20059 ABSTRACT · We present the construction and properties of a self-dual perverse sheaf S0 whose cohomology fulfills some of the requirements of String theory as outlined in [1]. The · construction of this S0 utilizes techniques that follow from MacPherson-Vilonen [2]. Finally, we will discuss its properties as they relate to String theory. 1 Introduction In analyzing ways to move between Calabi-Yau manifolds, Green and Hubsch in [3], [4] showed there are cases within String theory that admit mildly singular target spaces. These mildly singular spaces, termed conifolds [3], [5], [6] consist of the usual smooth target spaces with the addition of zero-dimensional singularities that stratify these spaces. Since these spaces are singular, the usual techniques for calculating cohomology do not apply. Ideally, a cohomology theory for String theory would apply to both smooth and not ‘too’ singular target spaces2 so that determination of stringy vacua could be possible in all cases. In an effort to qualify the mathematical requirements for this (co)homology theory, Hubsch proposed in [7] a working definition for a homology theory for String theory in the case of a mildly degenerate target space. This is recalled in the following definition. Definition 1.1. Let Y be a 2n-dimensional stratified space with a single isolated singularity, y. Then Hk(Y ), k>n; SHk(Y )= Hn(Y − y) ∪ Hn(Y ), k; (1.1) Hk(Y − y), k<n The middle dimension case, k, Hn(Y − y) ∪ Hn(Y ) is a qualitative way of expressing the String theory requirement arXiv:0704.3298v5 [math.AT] 20 May 2009 that the homology group contain cycles from both Hn(Y − y) and Hn(Y ).

In particular, we analyze the intersections of Iwahori orbits and semi-infinite orbits in the affine Grassmannian and affine flag variety. These intersections have interesting geometric and topological properties, and are related to representation theory. Moreover, we study the central degeneration (the degeneration that shows up in local models of Shimura varieties and Gaitsgory's central sheaves) of semi-infinite orbits, Mirkovi´c- Vilonen (MV) Cycles, and Iwahori orbits in the affine Grassmannian of type A, by considering their moment polytopes. We describe the special fiber limits of semi-infinite orbits in the affine Grassmannian by studying the action of a global group scheme. Moreover, we give some bounds for the number of irreducible components for the special fiber limits of Iwahori orbits and MV cycles in the affine Grassmannian. Our results are connected to Gaitsgory's central sheaves, affine Schubert calculus and affine Deligne-Lusztig varieties in number theory.

The workshop brought together experts investigating algebraic Lie theory from the geometric and combinatorial points of view. Mathematics Subject Classification (2000): 14Lxx, 17Bxx, 20Gxx. Introduction by the Organisers The workshop Enveloping Algebras and Geometric Representation Theory orga- nized by Shrawan Kumar (Chapel Hill), Peter Littelmann (K¨oln) and Wolfgang Soergel (Freiburg) was held March 4th—March 10th, 2012. It continues a series of conferences on enveloping algebras, as is indicated by the first part of the title, but the main focus was on geometric and combinatorial methods in algebraic Lie theory. The meeting was attended by over 50 participants from all over the world, in- cluding quite a few younger researchers. We had usually three talks in the morning and two in the afternoon, leaving ample time for discussions, which was amply used by the participants. Wednesday afternoon was reserved for an excursion to Sankt Roman, and on Thursday afternoon we had four shorter talks by younger par- ticipants. In addition, we had an ‘open problem’ session on Thursday evening preceding the social evening. Particularly interesting seemed to us the work of Leclerc and Hernandez on the Grothendieck rings of certain representations of quantum loop enveloping algebras and its relation to certain twisted derived Hall algebras; The work on geometrically killing the dynamical Weyl group by Ginzburg; the solution to the so-called AGT- conjecture of Alday, Gaiotto and Tachikawa by Vasserot; and the proof of Kostant’s 734 Oberwolfach Report 13/2012 Clifford algebra conjecture by Joseph; he work of Ian Gordon and Ivan Losev on category for cyclotomic rational Cherednik algebras, establishing in this case a derived equivalenceO between different blocks conjectured in general by Rouquier.
