SUMMARY:Higher rank Teichmüller spaces\, Higgs bundles and magical triples
DESCRIPTION:Oberseminar Algebra und Geometrie \nAndré Oliveira (Universidade do Porto) \nOne way to realize Teichmüller space of a closed oriented hyperbolic surface Σ is as the space of discrete and faithful representations π_1(Σ) -> PSL(2\,R). These constitute a connected component of the character variety of these representations. Higher rank Teichmüller space is a generalization for higher rank Lie groups. More precisely a higher rank Teichmüller space for a group G is a connected component of the G-character variety of representations π_1(Σ) -> G entirely consisting of discrete and faithful representations.\n\nThere are however two important differences comparing to the PSL(2\,R)-case. Firstly\, such spaces do not exist for any group G\, even though their existence has long been established whenever G is a split form (the Hitchin components) or Hermitian (maximal components). Secondly\, even if they exist for G\, not every discrete and faithful representation in G lies in a higher rank Teichmüller space. It was conjectured by Guichard—Labourie—Wienhard that the representations comprising such spaces are positive representations — a special class of discrete and faithful representations — which only exist when G admits a certain structure called positivity.\n\nNon-abelian Hodge theory yields corresponding connected components of the moduli space M(G) of G-Higgs bundles over an associated compact Riemann surface. We will introduce the notion of magical sl_2-triple and show that a group admits a positive structure if and only if it arises from such a magical triple. Then we we will use these magical triples and Higgs bundles to detect and parameterize components of M(G) which should be higher rank Teichmüller spaces (this was subsequently confirmed by Guichard—Labourie—Wienhard using our work). This is joint work with S. Bradlow\, B. Collier\, O. García-Prada and P. Gothen.\n

SUMMARY:Spectral decomposition and Siegel-Veech transforms: The case of marked tori
DESCRIPTION:International Seminar on Automorphic Forms \nMartin Möller (Goethe University Frankfurt) \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nAbstract: Generalizing the well-known construction of Eisenstein series on the modular curves\, Siegel-Veech transforms provide a natural construction of square-integrable functions on strata of differentials on Riemannian surfaces. Even the case of marked tori\, a homogeneous space but not for a reductive group provides features that we highlight in this talk with an eye on the general case.

SUMMARY:Counting congruences between modular forms
DESCRIPTION:Jaclyn Lang (Temple University\, Philadelphia) \nFor a given eigenform\, how many other eigenforms of the same weight and level are congruent to it modulo a prime l? We will explain how modular representation theory can be used to help answer this question. We focus especially on the case when the level is the square of a prime p such that p = -1 mod l. This is ongoing joint work with Robert Pollack and Preston Wake.

SUMMARY:Motivic cohomology of cyclic coverings
DESCRIPTION:Tariq Syed (Mainz) \nAbstract. The generalized Serre question asks whether algebraic vector bundles over topologically contractible smooth affine complex varieties are always trivial or not. Many examples of topologically contractible smooth affine complex varieties are given by so-called cyclic coverings. In this talk\, we present new results on the motivic cohomology of such cyclic coverings which might indicate a positive answer to the generalized Serre question in low dimensions.

SUMMARY:Symplectic singularities and vertex algebras
DESCRIPTION:Tomoyuki Arakawa (RIMS): Symplectic singularities and vertex algebras \nSymplectic singularities introduced by Beauville appear in various aspects of representation theory and are referred to as “21st-century Lie theory” by Okounkov. On theother hand\, symplectic singularities also arise in the context of quantum field theory in physics\, particularly in the Higgs and Coulomb branches of three-dimensional theories\, as well as in the Higgs branches of four-dimensional theories. \nAdditionally\, in vertex algebra theory\, certain Poisson varieties called associated varieties are defined as geometric invariants\, and they often turn out to be symplectic singularities. In such cases\, vertex algebras can be regarded as chiral noncommutative deformations of symplectic singularities. \nIn particular\, the 4D/2D duality proposed by Beem et al. in theoretical physics determines vertex algebras as invariants for superconformal four-dimensional theories. It is claimed that the Higgs branch of four-dimensional theories can be reconstructed as the associated variety of vertex algebras. Therefore\, all vertex algebras arising from four-dimensional theories are supposed to be chiral noncommutative deformations of singular symplectic varieties. \nIn this lecture\, we will discuss such vertex algebras and their representation theory.

SUMMARY:Salem numbers and short geodesics
DESCRIPTION:International Seminar on Automorphic Forms \nLola Thompson (Utrecht University): Salem numbers and short geodesics \nWe will discuss how Mahler measure and related concepts (e.g.\, Salem numbers) are connected to problems about lengths of geodesics on arithmetic hyperbolic manifolds. As a result\, by solving problems using tools from number theory\, we are able to answer quantitative questions in spectral geometry. This talk will build towards two goals: showing that short geodesics on arithmetic hyperbolic surfaces are rare\, and showing that\, on average\, geodesic lengths of non-compact arithmetic hyperbolic orbifolds appear with high multiplicity. This talk is based on joint work with Mikhail Belolipetsky\, Matilde Lalín\, and Plinio G. P. Murillo; and with Benjamin Linowitz\, D. B. McReynolds\, and Paul Pollack. \nhttps://tu-darmstadt.zoom.us/j/68048280736

SUMMARY:A local model for potentially Barsotti–Tate Galois representations
DESCRIPTION:Stefano Morra (Université Paris 8\, St. Denis): \nPotentially Barsotti–Tate deformations are an essential tool to achieve arithmetic results as the proof of the Shimura–Taniyama–Weyl conjecture\, or the Breuil–M´ezard conjecture. Nevertheless\, their geometry is still poorly understood\, as such rings showed a rich range of complicated behavior\, e.g. they may fail to be normal or regular (as shown in some examples and conjectures by Caruso–David–Mézard). In this talk we will discuss how moduli stack of Breuil–Kisin modules can be used to describe the geometry of moduli of tamely potentially Barsotti–Tate Galois representations (in rank 2 and over an unramified extension of Qp)\, using the theory of local models of loop groups in mixed characteristic. The main technical tool is an analysis of the p-torsion of a tangent complex to lift affine open charts for scheme–theoretic images between moduli of Breuil–Kisin modules and moduli of Galois representations. As a byproduct\, we obtain an algorithmic procedure to compute explicit presentations for any tamely potentially Barsotti–Tate deformation ring for 2-dimensional Galois representations of unramified extensions of Qp.\nThis is joint work with B. Le Hung and A. Mézard.

SUMMARY:F-modules for rings with FFRT\, and applications to local cohomology
DESCRIPTION:Eamon Quinlan-Gallego (Utah) \nAbstract: For a regular ring R of positive characteristic\, an F-module over R is an R-module equipped with an “action of Frobenius”. The theory of these F-modules has been used successfully in establishing finiteness properties of local cohomology\, and in this talk I will present an extension to the case where R is allowed to have mild singularities (known as finite F-representation type\, or FFRT for short). I will then illustrate how this theory can be used to extend previous results on local cohomology to the FFRT case.

SUMMARY:Heptagons\, quartics and theta characteristics
DESCRIPTION:Oberseminar Algebra und Geometrie \nDaniele Agostini  (Universität Tübingen) \nAbstract: A construction of Wachspress associates to a heptagon a plane  quartic curve. This has been recently reinterpreted from the point of view of positive geometry\, and numerical computations suggest that a general plane quartic arises from precisely 864 heptagons. We prove this rigorously\, via theta characteristics and the finite group PSL(2\,7). This is joint work with Daniel Plaumann\, Rainer Sinn and Jannik Weisner.

SUMMARY:On recent progress on the chiral de Rham complex and modular forms
DESCRIPTION:Xuanzhong Dai (RIMS): On recent progress on the chiral de Rham complex and modular forms \nThe Chiral de Rham complex introduced by Malikov et al. is a sheaf construction of vertex algebras on any smooth manifold or nonsingular algebraic variety. Applying this technique to the upper half plane\, we obtain a quantization of modular forms\, which recovers the Rankin-Cohen brackets\, a family of bilinear operations on modular forms. It has long been speculated that the Rankin-Cohen brackets are connected to vertex operator algebras\, as initially proposed by W. Eholzer\, Y. Manin\, and D. Zagier. Our construction naturally inherits a vertex algebra structure\, with the vertex operation fully determined by a slight modification of the Rankin-Cohen brackets.

SUMMARY:The fiber bundle method applied to triple product L-functions
DESCRIPTION:International Seminar on Automorphic Forms \nMiao Gu (University of Michigan): The fiber bundle method applied to triple product L-functions \nThe Poisson summation conjecture of Braverman-Kazhdan\, L. Lafforgue\, Ngô\, and Sakellaridis predicts that spherical varieties (or Whittaker induction thereof) over a global field admit a theory of Fourier analysis\, including a generalized Poisson summation formula. The fiber bundle method is a technique for proving the Poisson summation conjecture for spherical varieties that can be written as a family of simpler spherical varieties for which the Poisson summation conjecture is known. In this talk\, I will first explain how to relate a generalized Whittaker induction to triple product L-functions. Then I will explain the fiber bundle method and describe an approach to applying it to prove the expected analytic properties of the triple product L-functions. This is joint work with Jayce Getz\, Chun-Hsien Hsu\, and Spencer Leslie. \nhttps://tu-darmstadt.zoom.us/j/68048280736

SUMMARY:Counting Weierstrass points on degenerating algebraic curves
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Summer Semester 2024) \nLucas Gierczak (Institut Polytechnique de Paris) \nAbstract:\nWeierstrass points on algebraic curves are special points of high importance in algebraic geometry and arithmetic geometry. In this talk\, we study how those special points behave when the algebraic curve degenerates to a nodal curve. To this end\, we first explain why tropical geometry is a relevant formalism for studying degeneration questions. We then define a tropical analogue on metric graphs (seen as tropical curves) for Weierstrass points\, and explore the properties of the so-called “tropical Weierstrass locus”. We also associate intrinsic weights to the connected components of this locus\, and show that their total sum for a given metric graph and divisor is a function of few combinatorial parameters (degree and rank of the divisor\, genus of the metric graph). Finally\, in the case the divisor on the metric graph comes from the tropicalization of a divisor on an algebraic curve\, we specify the compatibility between the Weierstrass loci.

SUMMARY:The log tautological ring of the moduli space of curves
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (Second meeting Summer Semester 2024) \nPim Spelier (Universität Leiden) \nAbstract: \nThe tautological ring of Mgn-bar has been a crucial object in the study of the intersection theory of the moduli space of curves. Recently\, there has been more focus on the logarithmic enumerative geometry of Mgn-bar\, with interesting classes coming from e.g. log double ramification cycles. We present a definition of the log tautological ring of Mgn-bar\, together with a log decorated strata algebra\, and prove several structure results. The main new tools are the notions of cone stacks with boundary and homological piecewise polynomials\, that capture the tropicalisation of strata of log smooth stacks and the combinatorial part of their intersection theory.\nThis is joint work with Rahul Pandharipande\, Dhruv Ranganathan and Johannes Schmitt.
