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).

SUMMARY:Hodge Witt cohomology with modulus and duality
DESCRIPTION:Kay Rülling (Universität Wuppertal) \nAbstract: The theory of cube invariant modulus sheaves developed by Kahn-Miyazaki-Saito-Yamazaki allows to define for any sheaf with transfers and any smooth k-scheme X with effective Cartier divisor D a sheaf whose sections over X can be interpreted as regular sections on the complement of D with pole order at infinity bounded by D. This construction is functorial and has a certain universal property\, which makes it hard to compute explicitly. We apply it to the de Rham-Witt sheaves in positive characteristic p and show that in case the support of D has simple normal crossings these sheaves correspond under Grothendieck duality to de Rham Witt sheaves with zeros along D. From this we deduce refined versions of Ekedahl duality\, Poincaré duality for crystalline cohomology\, and Milne duality for motivic cohomology with p-primary torsion coefficients. This is joint work with Fei Ren. \nZoom Meeting-ID: 967 5163 9626 \nPasscode: last name of famous mathematician born in Königsberg (small letters)

SUMMARY:Linear Relations of 1-Periods
DESCRIPTION:Frankfurter Seminar – Kolloquium des Instituts für Mathematik \nAnnette Huber-Klawitter (Universität Freiburg) \nAbstract: 1-Periods are complex numbers obtained by integrating an algebraic $1$-form defined over $\mathbf{Q}$ (e.g. $dx/x$) over a chain with algebraic end points. The set contains many interesting numbers (e.g.\, the values of $\log$ in algebraic numbers). Their transcendence and the relations between them are a classical question of transcendence theory. \nWe now have complete picture\, explaining the relations qualitatively in terms of obvious relations and also quantitatively\, by which we mean dimension formulas. \nIn the talk we are going to explain some of these general results and then discuss the application to the values of the hypergeometric function–recovering results of Wolfart.

SUMMARY:Global theta correspondence mod p for unitary groups
DESCRIPTION:International Seminar on Automorphic Forms \nXiaoyu Zhang (University Duisburg-Essen) \nTheta correspondence is a very important tool in Langlands program. A fundamental problem in theta correspondence is the non-vanishing of the theta lifting of an automorphic representation. In this talk\, we would like to consider a mod p version of the non-vanishing problem for global theta correspondence for certain reductive dual pairs of unitary groups. We approach this by looking at the Fourier coefficients of the theta lifting and reduce the problem to the equidistribution of unipotent orbits. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Non-archimedean integration on quotients and BPS-invariants
DESCRIPTION:Seminar on Arithmetic Geometry \nDimitri Wyss (École Polytechnique Fédérale de Lausanne) \nIn previous work with F. Carocci and G. Orecchia we discovered that BPS-invariants appearing in Donaldson-Thomas theory for moduli of sheaves on del Pezzo surfaces admit a natural interpretation as non-archimedean integrals. Motivated by this\, we develop a non-archimedean integration theory for smooth Artin stacks and obtain as application a new expression of these BPS invariants. In particular this gives a new proof of Maulik-Shen’s $\chi$-independence result for del Pezzo surfaces. This is joint work in progress with Michael Groechenig and Paul Ziegler. \nZoom (635 7328 0984\, Password: smallest six digit prime).

SUMMARY:Automorphy Lifting with Ĝ-adequate image
DESCRIPTION:Dmitri Whitmore (University of Cambridge) \nLet F be a number field and G a (split) reductive group. The Langlands program attempts to relate\n(1) automorphic representations of G\n(2) representations of the absolute Galois group of F valued in Ĝ\, the dual group of G.\nAutomorphy lifting theorems are a way to go from (2) to (1). Such theorems are proved using the Taylor–Wiles method but require certain ‘big image’ hypotheses. \nWe discuss a generalization of the Taylor–Wiles method. Our generalization results in a weakened big image condition (Ĝ-adequate image)\, which turns out to hold under certain irreducibility hypotheses. We conclude with applications to modularity of some elliptic curves over quadratic extensions of totally real fields\, building on work of Boxer–Calegari–Gee–Pilloni.

SUMMARY:Arithmeticity of modular forms on G_2
DESCRIPTION:International Seminar on Automorphic Forms \nAaron Pollack (University of California San Diego) \nHolomorphic modular forms on Hermitian tube domains have a good notion of Fourier expansion and Fourier coefficients. These Fourier coefficients give the holomorphic modular forms an arithmetic structure: there is a basis of the space of holomorphic modular forms for which all Fourier coefficients of all elements of the basis are algebraic numbers. The group G_2 does not have an associated Shimura variety\, but nevertheless there is a class of automorphic functions on G_2 which possess a semi-classical Fourier expansion\, called the quaternionic modular forms. I will explain the proof that (in even weight at least 6) the cuspidal quaternionic modular forms possess an arithmetic structure\, defined in terms of Fourier coefficients. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).
