SUMMARY:The heart fan of an abelian category
DESCRIPTION:David Ploog (Stavanger) \nAbstract: To an abelian category such as coherent sheaves on a projective variety or modules over a finite-dimensional algebra\, I associate a fan of convex cones. This fan reflects homological properties of the category. It contains the g-fan of representation theory and is related to the stability conditions.

SUMMARY:Wall crossing for equivariant CY3 categories
DESCRIPTION:Nikolas Kuhn (University of Oxford) \nThe Joyce-Song wall-crossing formulas for Donaldson-Thomas invariants of Calabi-Yau threefolds have proven to be a crucial and versatile tool. In the presence of a torus action\, there are interesting threefold geometries in which the Calabi-Yau condition only holds up to an equivariant twist – examples include Vafa-Witten invariants\, local curves and surfaces and the threefold vertex. In these cases\, invariants are defined using localization\, and Joyce-Song’s theory doesn’t apply. I will explain how ideas from Joyce’s recent work on wall-crossing in abelian categories can be used to prove wall-crossing in this situation\, and which difficulties arise.  This is joint work with Henry Liu and Felix Thimm.

SUMMARY:Resolution of non-singularities and anabelian applications
DESCRIPTION:Emmanuel Lepage (IMJ Paris) \nAbstract: In various anabelian settings over p-adic fields\, one can reconstruct from the fundamental group of a hyperbolic curve the dual graph of the stable reduction of the curve\, and one can get more anabelian information on the curve by applying it to various finite étale covers. For each such finite étale cover\, this graph defines a retract of the analytic space associated to the curve (in the adic or Berkovich sense)\, and resolution of non-singularities predicts that the Berkovich space is homeomorphic to the inverse limit of all these retracts. This was proven in 2023 by Mochizuki and Tsujimura over finite extensions of Q_p. I will try to give a sketch of their proof and explain how to deduce a characterization of geometric Galois sections.

SUMMARY:p-adic higher Green's functions for Stark-Heegner Cycles
DESCRIPTION:International Seminar on Automorphic Forms \nHazem Hassan (McGill) \nHeegner Cycles are higher weight generalizations of Heegner points on Modular curves. As such\, one expects them to capture similar arithmetic and modular properties to Heegner points. The higher dimensional nature of Heegner cycles makes them less amenable to algebro-geometric and deformation theoretic approaches. I will introduce Stark-Heegner Cycles\, which are a conjectural analogue to Heegner Cycles in the theory of Real Multiplication. They are defined through p-adic analytic means. Then\, I will describe a p-adic pairing on these cycles which behaves as a local height pairing. When one of the cycles is principal\, the pairing computationally seems to produce algebraic integers living in class fields of real quadratic fields. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits)

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:Counting and equidistribution
DESCRIPTION:International Seminar on Automorphic Forms \nYiannis Petridis (UCL): Counting and equidistribution \nI will discuss how counting orbits in hyperbolic spaces lead to interesting number theoretic problems. The counting problems (and the associated equidistribution) can be studied with various methods\, and I will emphasize automorphic form techniques\, originating in the work of H. Huber and studied extensively by A. Good. My collaborators is various aspects of this project are Chatzakos\, Lekkas\, Risager\, and Voskou. \nhttps://tu-darmstadt.zoom.us/j/68048280736 \nThe password is the first Fourier coefficient of the modular j-function (as digits) \n

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:Seminar on Arithmetic Geometry
DESCRIPTION:Jens Eberhardt (Gutenberg Universität Mainz): K-motives and Local Langlands \nIn this talk\, we construct a geometric realization of the category of representations of the affine Hecke algebra and p-adic reductive groups.\nFor this\, we introduce a formalism of K-theoretic sheaves (called K-motives) on stacks.\nThe affine Hecke algebra arises from the K-theory of the Steinberg stack\, and we explain how to “categorify” this using K-motives. \nLastly\, we discuss applications of K-motives to the local geometric Langlands program. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl
