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).

SUMMARY:Equivariant localization theorems
DESCRIPTION:Seminar on Arithmetic Geometry \nCharanya Ravi (Indian Statistical Institute\, Bangalore Centre) \nThe classical Atiyah-Bott localization theorem in equivariant singular cohomology is one of the primary computational tools in enumerative geometry when the relevant parameter space has a natural torus action. The theorem asserts that the equivariant cohomology of a space with group action can be recovered\, up to inversion of some elements\, from the equivariant cohomology of the fixed point subspace. To understand various moduli problems\, there is a need to access general parameter spaces (singular and stacky) and to produce refined counts (in different cohomology theories). \nThis talk will first discuss a unified Atiyah-Bott localization theorem for equivariant Borel-Moore homology theories of algebraic stacks. We will then discuss a categorified version of the result which allows us to deduce the theorem for all oriented theories (cohomology and Borel-Moore homology). The talk is based on joint works with Dhyan Aranha\, Adeel Khan\, Alyosha Latyntsev\, and Hyeonjun Park. \nZoom (635 7328 0984\, Password: smallest six digit prime).

SUMMARY:Motivic cohomology of mixed characteristic schemes
DESCRIPTION:Tess Bouis (Université Paris-Saclay) \nAbstract:\nI will present a new theory of motivic cohomology for general (qcqs) schemes. It is related to non-connective algebraic K-theory via an Atiyah-Hirzebruch spectral sequence. In particular\, it is non-A1-invariant in general\, but it recovers classical motivic cohomology on smooth schemes over a Dedekind domain after A1-localisation. The construction relies on the syntomic cohomology of Bhatt-Morrow-Scholze and the cdh-local motivic cohomology of Bachmann-Elmanto-Morrow\, and generalises the construction of Elmanto-Morrow in the case of schemes over a field. \nZoom: \nMeeting-ID: 967 5163 9626 \nPasscode: last name of famous mathematician born in Königsberg (small letters)

SUMMARY:Various implications of the Nagao-Mestre sum
DESCRIPTION:Oberseminar Algebra und Geometrie \nSeoyoung Kim (Universität Göttingen) \nIn 1965\, Birch and Swinnerton-Dyer formulated a conjecture on the Mordell-Weil rank $r$ of elliptic curves which also implies the convergence of the Nagao-Mestre sum. We show that if the Nagao-Mestre sum converges\, then the limit equals $-r+1/2$\, and study the connections to the Riemann hypothesis for E. We also relate this to Nagao’s conjecture. Furthermore\, we discuss a generalization of the above results for the Selberg classes and hence (conjecturally) for larger classes of  $L$-functions.

SUMMARY:Siegel modular forms and higher algebraic cycles
DESCRIPTION:International Seminar on Automorphic Forms \nAleksander Horawa (University of Oxford) \nAbstract: In recent work with Kartik Prasanna\, we propose an explicit relationship between the cohomology of vector bundles on Siegel modular threefolds and higher Chow groups (aka motivic cohomology groups). For Yoshida lifts of Hilbert modular forms\, we use a result of Ramakrishnan to prove our conjecture. For Yoshida lifts of Bianchi modular forms\, we show that our conjecture implies the conjecture of Prasanna—Venkatesh. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits).

SUMMARY:Monodromy of subrepresentations and irreducibility of low degree automorphic Galois representations

SUMMARY:Spherical Tropicalization and Berkovich Analytic Groups
DESCRIPTION:Oberseminar Algebra und Geometrie \nDesmond Coles (Univ. of Texas\, Austin) \nAbstract: Tropicalization is the process by which algebraic varieties are assigned a “combinatorial shadow”. I will review the notion of tropicalization of a toric variety and recent work on extending this to spherical varieties. I will then present how one can construct a deformation retraction from the Berkovich analytification of a spherical variety to its tropicalization.

SUMMARY:Real analogue of the arithmetic K-theory
DESCRIPTION:Bo Liu (East China Normal University) \nDifferential K-theory is a new research field in the 21st century which is motivated by the study of superstring theory in theoretical physics. It is the differential extension of the topological K-theory and can be regarded as the real analogue of the arithmetic\nK-theory in Arakelov geometry\, which is the arithmetic extension of the K-theory introduced by Grothendieck. In this talk\, we will discuss the properties of differential K-theory by comparing them with corresponding properties of arithmetic K-theory and use them to derive some new geometric results. In particular\, we will obtain the localization\nformulas for eta invariants and eta forms from the localizations in differential K-theory. \nhttps://tu-darmstadt.zoom-x.de/j/67833963376?pwd=eHVYZDZaRFBUdFZMZjM5K1RnYXRSQT09 \nMeeting ID: 678 3396 3376\nPasscode: 222561

SUMMARY:A gentle introduction to derived blow-ups
DESCRIPTION:Jeroen Hekking (Universität Regensburg) \nDerived blow-ups of classical schemes in quasi-smooth centers were first introduced by Kerz\, Strunk and Tamme to solve Weibel’s conjecture on the vanishing of negative algebraic K-theory groups. This was generalized to quasi-smooth closed immersions of derived Artin stacks by Khan and Rydh\, which has found applications in virtual intersection theory. In joint work with Khan–Rydh\, this is further generalized to allow derived blow-ups in arbitrary centers. These were used in joint work with Rydh–Savvas to give a derived reduction of stabilizers algorithm. \nThe goal of this talk is to give an overview of some of the key ideas of this story which is accessible to geometers in general. We will pay particular attention to why derived algebraic geometry is useful\, even if one is ultimately only interested in classical geometry.

SUMMARY:Prismatic Windows with Additional Structures
DESCRIPTION:Mohammad Hadi Hedayatzadeh (Institute for Research in Fundamental Sciences\, Tehran) \nIn this talk\, I will present a joint work with O. Bültel and my student A. Partofard on prismatic windows with additional structures. I will start with a brief overview of the theory of displays\, developed by Th. Zink\, which is a generalization of Dieudonné theory. Displays play a crucial role in the study of Barsotti-Tate groups when the base is not a perfect field of positive characteristic. Zink has further developed the theory and introduced windows over frames. In another direction\, in order to construct integral models of Shimura varieties that are not of Abelian type\, O. Bültel defined and studied displays with additional structures\, called (G\,μ)-displays. In this joint work\, we combine these two inventions to define and study (G\,μ)-windows and show that under some mild conditions\, the category of (G\,μ)-windows is equivalent to that of (G\,μ)-displays. Finally\, in a joint project with Partofard\, we develop the theory of prismatic windows\, which is better adapted to the setting of pefectoid geometry and is closely related to the stack of G-torsors over the Fargues-Fontaine curve. \n
