SUMMARY:Murmurations of holomorphic modular forms in the weight aspect
DESCRIPTION:International Seminar on Automorphic Forms \nMin Lee (University of Bristol) \nIn April 2022\, He\, Lee\, Oliver\, and Pozdnyakov made an interesting discovery using machine learning – a surprising correlation between the root numbers of elliptic curves and the coefficients of their L-functions. They coined this correlation ‘murmurations of elliptic curves.’ Naturally\, one might wonder whether we can identify a common thread of ‘murmurations’ in other families of L-functions. In this talk\, I will introduce a joint work with Jonathan Bober\, Andrew R. Booker and David Lowry-Duda\, demonstrating murmurations in holomorphic modular forms. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Theta functions for the projective plane relative a smooth cubic
DESCRIPTION:Seminar on Arithmetic Geometry \nHelge Ruddat (University of Stavanger) \nGross-Hacking-Siebert generalized the classical Jacobi theta function from abelian varieties to more general log Calabi-Yau manifolds. Landau-Ginzburg superpotentials in mathematical physics give particular examples of such theta functions. Zaslow\, Gräfnitz and I compute the Landau-Ginzburg superpotential of the mirror symmetry dual of P^2 relative a smooth elliptic curve. This infinite power series is tropically defined and can be identified with a generating function for 2-contact point rational Gromov-Witten invariants of (X\,E). We found that this series also equals the open mirror map for outer Aganagic-Vafa branes in the canonical bundle K_X\, so it is closely related to a solution to a Lerche-Mayr system of two differential equations and it is also a generating function of holomorphic disk counts. The fundamental structure used to study theta functions is the wall structure. I am going to explain the background and usefulness of this recent technology. \nZoom (635 7328 0984\, Password: smallest six digit prime).

SUMMARY:Wonderful compactification over an arbitrary base scheme
DESCRIPTION:Seminar on Arithmetic Geometry \nWonderful compactifications of adjoint reductive groups over an algebraically closed field play an important role in algebraic geometry and representation theory. In this talk\, we will construct an equivariant compactification for adjoint reductive groups over arbitrary base schemes\, which parameterize classical wonderful compactifications of De Concini and Procesi as geometric fibers. Our construction is based on a variant of the Artin–Weil method of birational group laws. In particular\, our construction gives a new intrinsic construction of wonderful compactifications. If time permits\, we will also discuss several applications of our compactification in the study of torsors under reductive group schemes. \nShang Li (Paris-Saclay University) \nZoom (635 7328 0984\, Password: smallest six digit prime).

SUMMARY:A "Galois" categorical p-adic local Langlands for GL(2\,Qp)
DESCRIPTION:Christian Johansson (Universität Göteborg) \nI will introduce the p-adic local Langlands correspondence for GL(2\,Qp)\, in the forms established by Colmez and Paskunas\, and then give an interpretation of it as an embedding of categories (a form of “localization”). Time permitting\, I will also discuss local-global formulas for singular cohomology of modular curves that you can get from this framework. This is joint work with James Newton and Carl Wang-Erickson.

SUMMARY:Restricted Arithmetic Quantum Unique Ergodicity
DESCRIPTION:International Seminar on Automorphic Forms \nThe quantum unique ergodicity conjecture of Rudnick and Sarnak concerns the mass equidistribution in the large eigenvalue limit of Laplacian eigenfunctions on negatively curved manifolds. This conjecture has been resolved by Lindenstrauss when this manifold is the modular surface assuming these eigenfunctions are additionally Hecke eigenfunctions\, namely Hecke-Maass cusp forms. I will discuss a variant of this problem in this arithmetic setting concerning the mass equidistribution of Hecke-Maass cusp forms on submanifolds of the modular surface. \nPeter Humphries (University of Virginia) \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Combing a hedgehog over a field
DESCRIPTION:Alexey Ananyevskiy (LMU München) \nA classical result in differential topology says that there are no nowhere vanishing vector fields on a 2-sphere. One may ask a similar question in algebraic geometry: does the tangent bundle to a sphere given by the equation x^2+y^2+z^2=1 over some field k have a nowhere vanishing section? Or more generally\, when does the tangent bundle on an affine quadratic q=1 with q being a homogeneous degree 2 polynomial have a nowhere vanishing section? We give an essentially full answer to this question assuming that the quadric q=1 has a rational point. In particular\, the 2-sphere x^2+y^2+z^2=1 over a field k has a nowhere vanishing vector field if and only if -1 is a sum of 4 squares in k. The proof uses a mixture of results from the motivic homotopy theory\, Chow-Witt rings and some constructions from the theory of quadratic forms.\nThis is a joint work with Marc Levine. \nZoom Meeting-ID: 967 5163 9626 \nPasscode: last name of famous mathematician born in Königsberg (small letters)

SUMMARY:Around the Gauss circle problem
DESCRIPTION:International Seminar on Automorphic Forms \nSteve Lester (King’s College London) \nHardy conjectured that the error term arising from approximating the number of lattice points lying in a radius-R disc by its area is O(R^{1/2+o(1)}). One source of support for this conjecture is a folklore heuristic that uses i.i.d. random variables to model the lattice points lying near the boundary and square-root cancellation of sums of these random variables. In this talk I will examine this heuristic and discuss how lattice points near the circle interact with one another. This is joint work with Igor Wigman. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Drinfeld modular forms of arbitrary rank and their partial derivatives
DESCRIPTION:Oğuz Gezmiş (Universität Heidelberg) \nIn the 1980s\, David Goss introduced Drinfeld modular forms in the rank two case where the analogy with the setting of elliptic modular forms was quite striking. Recently\, using the work of Häberli and Pink\, Basson\, Breuer\, and Pink successfully generalized the theory of Drinfeld modular forms to the arbitrary rank setting and provided explicit examples. In this talk\, we describe several identities on the derivatives of Drinfeld modular forms of higher rank and introduce a differential operator acting on the space of such forms. Moreover\, we construct a finitely generated algebra containing all the Drinfeld modular forms for the full modular group and discuss its stability under partial derivatives as well as the transcendence of its generators at CM points. This is a joint work with Yen-Tsung Chen. \n

SUMMARY:Bordism of commuting involutions
DESCRIPTION:Markus Hausmann (Bonn) \nAbstract: The bordism ring of manifolds equipped with an involution was computed additively by Conner-Floyd (1965) and multiplicatively by Alexander (1972). Alexander’s description is explicit but complicated and doesn’t seem to enjoy a simple algebraic interpretation.\nIn this talk I will discuss that if one extends the problem and\n1) considers the collection of bordism rings of manifolds with n commuting involutions for all n\, and\n2) takes into account the representation sphere-grading\,\nthen there is a simple algebraic universal property. \nThis is joint work with Stefan Schwede. \nZoom Meeting-ID: 967 5163 9626 \nPasscode: last name of famous mathematician born in Königsberg (small letters)

SUMMARY:Harris–Venkatesh plus Stark
DESCRIPTION:International Seminar on Automorphic Forms \nRobin Zhang (Massachusetts Institute of Technology) \nThe class number formula describes the behavior of the Dedekind zeta function at $s = 0$ and $s = 1$. The Stark and Gross conjectures extend the class number formula\, describing the behavior of Artin $L$-functions and $p$-adic $L$-functions at $s = 0$ and $s = 1$ in terms of units. The Harris–Venkatesh conjecture describes the residue of Stark units modulo $p$\, giving a modular analogue to the Stark and Gross conjectures while also serving as the first verifiable part of the broader conjectures of Venkatesh\, Prasanna\, and Galatius. In this talk\, I will draw an introductory picture\, formulate a unified conjecture combining Harris–Venkatesh and Stark for weight one modular forms\, and describe the proof of this in the imaginary dihedral case. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Embedded normality in affine Grassmannians
DESCRIPTION:Seminar on Arithmetic Geometry \nJoão Lourenço (University of Münster) \nAbstract: Let k/F_p be an algebraically closed field and let G be any connected reductive group over a Laurent series field. To a given parahoric group model of G\, we can consider its affine Grassmannian which carry interesting parahoric orbit closures\, called Schubert varieties. It is known that these are always normal\, Cohen-Macaulay\, rational\, etc. for almost all G\, provided p is not torsion for G_der. The general strategy of proof goes back to Faltings\, but it is far from ideal\, as it relies on at least two constructions that cannot be done uniformly for all G. In this talk\, I’ll explain a new proof that circumvents this via two techniques: inversion of adjunction for splinters following Bhatt et al. (joint with Cass); and a Serre presentation for distributions of loop groups. \nZoom (635 7328 0984\, Password: smallest six digit prime).
