SUMMARY:Explicit methods for enumerative invariants using Siegel and mock modular forms: The K3 case
DESCRIPTION:Abhiram Kidambi (MPI Leipzig) \nAbstract: A conjecture for nearly two decades on the interface of algebraic geometry\, number theory and topological string theory is the OSV conjecture which conjectures a form for the generating function of (certain) rank 0 Donaldson-Thomas invariants for CY threefolds\, and this formulation goes hand in hand with understanding wall crossing phenomena. On the automorphic forms side\, one often encounters mock modular forms and iterated integrals thereof. To understand the precise relation between mock-modularity\, OSV conjecture is an open problem as well. \nThere are many problems in the same spirit\, and we will visit the problem in the case of K3 surfaces and symmetric powers thereof.  This case is a particularly nice exercise since the analogue of the OSV conjecture is a bit more restrictive (because there is only one polynomial term in the formal power series expansion which is needed to compute the enumerative invariants). This allows us to compute things rather explicitly using the theory of mock modular/Jacobi forms. Of particular interest are special points (called attractor points) where the generating function for enumerative invariants follow an OSV-type behaviour. \nIn this (chalk) talk\, I will start with the statement of the problem for this particular case\, introduce all the necessary objects (Siegel modular forms\, mock modular forms\, Jacobi forms) and explain how one can construct the generating function for enumerative invariants at special points (and generic points if time permits). \nA conjecture for nearly two decades on the interface of algebraic geometry\, number theory and topological string theory is the OSV conjecture which conjectures a form for the generating function of (certain) rank 0 Donaldson-Thomas invariants for CY threefolds\, and this formulation goes hand in hand with understanding wall crossing phenomena.

SUMMARY:On local Galois deformation rings
DESCRIPTION:Julian Quast (Universität Duisburg-Essen) \nIn joint work with Vytautas Paškūnas\, we show that the universal framed\ndeformation ring of an arbitrary mod p representation of the absolute\nGalois group of a p-adic local field valued in a possibly disconnected\nreductive group G is flat\, local complete intersection and of the\nexpected dimension. In particular\, any such mod p representation has a\nlift to characteristic 0. The work extends results of Böckle\, Iyengar\nand Paškūnas in the case G=GL_n. We give an overview of the proof of\nthis main result.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Can Yaylali (TU Darmstadt): A^1-homotopy theory of rigid analytic spaces\nIn this talk\, I will report about work with Christian Dahlhausen (Heidelberg) on A^1-homotopy theory of rigid analytic spaces. The B^1-homotopy category has already been defined and studied by Ayoub and a full six-functor formalism was established by Ayoub-Gallauer-Vezzani. One drawback of the B^1-invariant theory is that analytic K-theory for rigid analytic spaces (as defined and studied by Kerz-Saito-Tamme) is not representable since it is not B^1-invariant. Thus we aim for an A^1-invariant version with coefficients in any presentable category. For the stable theory\, we can prove the existence of a partial six-functor formalism for analytifications of schemes and algebraic morphisms between them by using the results of Ayoub’s thesis. Furthermore\, using coefficients in condensed spectra\, we can represent analytic K-theory as the P^1-ring spectrum Z x BGL. If time permits I will also highlight some of the remaining questions. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl

SUMMARY:Towards results on the anticyclotomic Iwasawa theory of modular forms at inert primes via diagonal classes
DESCRIPTION:Luca Marannino (IMJ-PRG Paris) \nIn this talk we outline an approach to the study of anticyclotomic Iwasawa theory of modular forms when the fixed prime p is inert in the relevant quadratic imaginary field. Following ideas of Castella-Do and Alonso-Castella-Rivero for the “p split” case\, one can envisage a construction of an anticyclotomic Euler system arising from a suitable manipulation of diagonal cycles (considered in previous works of Darmon-Rotger and Bertolini-Seveso-Venerucci). We will report on this work in progress\, trying to underline the main difficulties arising in the “p inert” setting.

SUMMARY:The tropical 1-fold Abel-Prym map
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (First meeting Winter Semester 2024/25) \nGiusi Capobianco (Università di Roma Tor Vergata)\n\n\n\nAbstract: The algebraic Abel-Prym map relates the geometry of a double cover of algebraic curves with their corresponding Prym varieties. Birkenhake and Lange proved that the map has degree 2 if and only if the cover curve is hyperelliptic.\n\nIn the talk I will present joint work with Yoav Len\, in which we investigate the 1-fold Abel-Prym map in the tropical setting and prove similar results. I will describe a new combinatorial construction of hyperelliptic double covers of metric graphs and prove that the tropical Abel-Prym map is a harmonic morphism of degree 2.  Furthermore\, we will see that the Jacobian of the image of this map is isomorphic\, as pptav\, to the Prym variety of the cover. When the double cover is not hyperelliptic however\, contrary to the algebraic result\, the tropical Abel-Prym map is almost never injective. I will provide counterexamples and discuss its image.

SUMMARY:Tree spaces in tropical geometry
DESCRIPTION:TGiF-Seminar: Tropical geometry in Frankfurt (First meeting Winter Semester 2024/25) \nShelby Cox (MPI Leipzig)\n\nAbstract: The space of phylogenetic trees on n leaves arises naturally in tropical geometry through the tropical Grassmannian trop Gr(2\,n). The space of equidistant trees on n leaves is the tropicalization of M_{0\,n}\, which is tropically convex. In this talk\, I will present recent work using tropical tree spaces for phylogenetic statistics and inference (joint with Curiel\, Sabol\, Talbut\, and Yoshida). I will also discuss a conjectural analogue of the space of equidistant trees for type C (joint with Igor Makhlin).

SUMMARY:Kudla-Millson lift on the symmetric space of SL_N
DESCRIPTION:International Seminar on Automorphic Forms \nRomain Branchereau (McGill University): Kudla-Millson lift on the symmetric space of SL_N \nI will present a construction of a map from the homology in degree N-1 of locally symmetric spaces associated to SL_N\, to modular forms of weight N. The image of a cycle C by this map is a modular form whose Fourier coefficients are intersection numbers between C and a family of generalized modular symbols on the locally symmetric space. This map can be seen as a Kudla-Millson theta lift for the dual pair (SL_N\, SL_2) and also resembles a construction of Bergeron-Charollois-Garcia. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits) \n

SUMMARY:Abstract six-functor formalisms in Motivic Homotopy Theory
DESCRIPTION:Chirantan Chowdhury (TU Darmstadt) \nThe six functor formalism was formulated by Grothendieck to give a framework for the basic operations and duality statements for cohomology theories. In this talk\, I shall give an overview of abstract six-functor formalisms in the language of $\infty$-categories followed by its applications in the setting of Motivic Homotopy Theory. After introducing the setup\, we shall show how one can extend such formalism from smaller to larger categories (for e.g. : schemes to algebraic stacks). If time permits\, I would like to explain further extensions of such results to non-representable situations (joint work with Alessandro D’Angelo).

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Maximilian Hauck (MPIM Bonn): Stacks in the p-adic Hodge theory of formal schemes \nI will briefly review the stacky approach to p-adic cohomology theories due to Bhatt–Lurie and Drinfeld using a new view on the filtered prismatisation recently found by Gardner–Madapusi. Then I will show how to use these tools to obtain a new proof of the Beilinson fibre square of Antieau–Mathew–Morrow–Nikolaus and a generalisation of a comparison theorem between rational arithmetic étale cohomology and crystalline cohomology of Colmez–Niziol. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl
