SUMMARY:Fibering out Calabi-Yau motives\, the asymptotic of higher genus invariants and black hole physics
DESCRIPTION:Mirror symmetry implies that the higher genus Gromov-Witten (GW)\, Pandharipande-Thomas (PT) and\ncertain Donaldson-Thomas (DT) invariants on the A-model side are encoded in generating functions which are related to analytic\nsections of line bundles over the complex moduli space on the B-model side constructed from the periods. This relates the\nasymptotic behaviour of the invariants as extracted at the point of maximal unipotent monodromy to the behaviour of these sections\nnear the closest singularities\, typically a conifold. Here the relevant analytic information is encoded in closed and open\nmodular period integrals over the modular domain of $\Gamma_0(N)$. The latter structures are determined by properties\nof the degenerate Calabi-Yau motive in the conifold fibre\, which have been proven by the fibering out technique with B\”onisch and\nGolyshev. We comment on the implications of the asymptotic behaviour of the symplectic invariants for the estimates of the\nmicroscopic entropy of supersymmetric black holes and black rings as investigated recently with Alexandrov and Pioline.

SUMMARY:International Seminar on Automorphic Forms
DESCRIPTION:Faltings heights and subleading terms of adjoint L-functions\nRyan Chen (Princeton) \nColmez’s conjecture predicts that Faltings heights of CM abelian varieties appear in subleading terms of certain Artin L-functions. An averaged version is known by the work of Andreatta–Goren–Howard–Madapusi and Yuan–Zhang. We propose a generalized problem relating diagonal cycles on (n-1)-dimensional unitary Shimura varieties and adjoint L-functions of certain automorphic representations of U(n). The case n=1 is (a variant of) the averaged Colmez conjecture. I will explain some origins of our conjecture\, discuss our predictions in the general case\, and report on our results in the case in the case of n = 2\, via trace formula. This is joint work in progress with Weixiao Lu and Wei Zhang. \nZoom (680 4828 0736\, The password is the first Fourier coefficient of the modular j-function (as digits)).

SUMMARY:AGTZ Kolloquium
DESCRIPTION:Konstantin Emming (Wayne State University) \nTitle: Filtrations in C-motivic stable homotopy theory \nEmpirical evidence suggests that there is an interesting class of motivic spectra (containing  for example the sphere spectrum and Hermitian K-theory) whose effective  motivic slices are indexed by the Adams-Novikov E_2-page of their Betti realizations. In this talk\, we will show that there are more C-motivic spectra satisfying this property. For example\, the C-motivic modular forms spectrum mmf. Our approach to this problem will also recompute the slices of the aforementioned spectra. \nThe results rely on the filtered spectrum model for C-motivic (stable\, cellular\, 2-complete) homotopy theory due to Gheorghe-Isaksen-Krause-Ricka. We construct filtered spectrum models for the effective filtration and use these to compute the effective slices. \nIf time permits\, we will also consider other motivic filtrations such as the one coming from Morel’s homotopy t-structure\, or Spitzweck-Østvær’s very effective filtration. We will then provide filtered spectrum versions of these filtrations in C-motivic homotopy theory.

SUMMARY:p-adic singular moduli and higher Green’s functions
DESCRIPTION:Hazem Hassan (Mc Gill University / Universität Heidelberg) \n\nHeegner cycles are the higher weight analogues to Heegner points. Those points and cycles play an important role in the theory of complex multiplication and of the arithmetic of elliptic curves of rank 1. Stark-Heegner points are conjectural points on elliptic curves which would be the real-quadratic counterparts to Heegner points in the emerging theory of real multiplication. In this theory\, Darmon-Vonk’s rigid meromorphic cocycles seem to be the real-quadratic analogue of singular moduli.\n\nI will present a generalization of rigid meromorphic cocycles to higher weight and use it to define a p-adic higher Green’s functions on real-quadratic points. This construction is motivated by the recently resolved conjecture by Gross and Zagier  on the algebraicity of values of complex higher Green’s functions. I will present a conjecture on the algebraicity of values of the p-adic Green’s functions that has been numerically verified. The values of the p-adic Green’s function are best envisioned as p-adic local intersection numbers of certain conjectured cycles associated to RM-points\, the so-called Stark-Heegner cycles.

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Vukašin Mihajlović (Darmstadt): Central Sheaves for Ramified Groups \nOne of the main obstacles with trying to transfer classical results in geometric representation theory to the language of motives is the lack of a good notion of t-structure on the full category DM which would play the role of the perverse t-structure in the classical setting. However\, when the spaces considered have stratifications with a nice enough geometry\, one can still formulate some results motivically by restricting our category of motivic sheaves to certain nice subcategories\, like those of Tate or Artin-Tate motives. However\, these subcategories don’t automatically inherit the good categorical properties of DM\, as they are not stable under the six operations. Here is where one needs to prove\, by looking into the geometry of our problem more carefully\, that the functors of interest to our setup do indeed preserve these subcategories. In this talk\, we will do this for the case of the central functor applied to the BD Grassmannian of a twisted group. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl)

SUMMARY:Seminar on Arithmetic Geometry
DESCRIPTION:Yanik Kleibrink (Darmstadt): Period Maps from Log Prismatic Realization Functors \nI will start by surveying the recent development of logarithmic prismatic cohomology by Koshikawa and Yao that extends the original work by Bhatt and Scholze. In particular\, I will introduce the logarithmic prismatic realization functor for toroidal compactifications of integral canonical models of Shimura varieties of Hodge type constructed by Inoue\, which extends the realization functor of Imai\, Kato\, and Youcis. Using this realization functor\, I will present work-in-progress concerning the definition of a mod \(p\)-period map of the special fiber of an integral canonical model of Shimura variety of Hodge type to the stack of \(G\Zip\)s. Ideally\, this construction coincides with an existing construction by Goldring and Koskivirta and enables the usage of prismatic methods in the study of Ekedahl-Oort strata. \nZoom (635 7328 0984\, Kenncode: kleinste sechsstellige Primzahl)

SUMMARY:Oberseminar Algebra und Geometrie
DESCRIPTION:Menelaos Zikidis (University of Pittsburgh): Joyce Structures on Moduli of Quadratic Differentials \nAbstract: Joyce Structures are the output of Bridgeland’s largely conjectural program aiming to encode the DT- invariants of triangulated CY3 categories in a geometric structure over their space of stability conditions\, akin to Frobenius structures in GW-theory. In this talk I will concentrate on the main class of examples we can currently construct a Joyce structure\, namely on certain categories associated to quivers with potential. In those cases\, the space of stability conditions becomes the moduli of meromorphic quadratic differentials on wild algebraic curves and Joyce structures arise as isomonodromy connections on a space parametrising irregular parabolic Higgs bundles and flat connections\, a model resembling a complexification of the Hitchin system. These structures naturally give rise to a class of complex Hyperkähler manifolds and admit a twistor space description. \n  \n
