Workshop on "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory"

Workshop on "Combinatorics, Resurgence and Algebraic Geometry in Quantum Field Theory", August 19 - 23, 2024

The study of perturbative quantum field theory has shown a surprising need for the latest advances in algebraic geometry and combinatorics. The field also incorporates the very actively developed theory of resurgence, which has promising potential for applications to both topology and quantum field theory.

This workshop aims to advance this field by bringing together top experts. The goal is to foster discussions on recent results, encourage collaboration, generate new ideas, explore the connections in perturbative quantum field theory, and offer a platform for junior researchers.

This workshop consists of a fixed list of participants. It is not possible to register.

Workshop on "Dualisable Categories & Continuous K-theory", September 9 - 13, 2024

Algebraic K-theory is an object that sits at the centre of large parts of algebra, geometry, and topology because of its universal role as a receptacle to count other mathematical objects with signs. However, since its invention, a phenomenon often called the Eilenberg swindle - which says that the algebraic K-theory of a category which is too large must necessarily be zero - has been accepted as a fundamental limit to the theory.

Workshop on "Unstable Homotopy Theory", November 11 - 15, 2024

Unstable homotopy theory is about understanding the detailed structure and properties of topological spaces and morphisms between them. Central to this study is the concept of homotopy types (also known as ∞-groupoids, animas, or spaces), which classify topological spaces up to weak homotopy equivalence.

Heights and periods of homologically trivial cycles in families, I (live stream)

In these two talks, we consider the Beilinson—Bloch heights and Abel—Jacobian periods  of homologically trivial Chow cycles in families. For the Beilinson-Bloch  heights, we show that for any  $g>2$, there is a non-empty Zariski open subset $U$ of $M_g$, the coarse moduli of curves of genus $g$ over rationals, such that the heights of Ceresa cycles and Gross—Schoen cycles over $U$ satisfy the Northcott property.

Formal-analytic arithmetic surfaces are arithmetic analogues of germs of formal surfaces along a proper curve over some base field, in the same way as arithmetic surfaces are analogues of projective algebraic surfaces over some base field. It is possible to develop a  calculus  on formal-analytic arithmetic surfaces, involving Hermitian vector bundles and suitably defined arithmetic intersection numbers à la Arakelov. This calculus admits applications to finiteness results concerning the étale fundamental group of arithmetic surfaces, notably of integral models of modular curves.

This is a report on work in progress with Beuzart-Plessis and Thorne. Let G be a quasi-split group over a local field K of positive characteristic p. We show, conditionally on the existence of a version of the twisted trace formula adequate for stable cyclic base change, that every irreducible parameter of the Weil group of K with values in the L-group of G is the image of a (necessarily) supercuspidal representation of G(K) under the local parametrization constructed by Genestier-Lafforgue  and Fargues-Scholze.

Faltings heights and the sub-leading terms of adjoint L-functions (live stream)

The Kronecker limit formula may be interpreted as an equality relating the Faltings height of an CM elliptic curve to the sub-leading term (at s=0) of the Dirichlet L-function of an imaginary quadratic character. Colmez conjectured a generalization relating the Faltings height of any CM abelian variety to the subheading terms of certain Artin L-functions. An averaged (over all abelian varieties with CM by the integer ring of a given CM field) version was proved by Andreatta—Goren—Howard—Madapusi and Yuan—Zhang.

Taut foliations from knot diagrams

Taut foliations have been a classical object of study in 3-manifolds theory. Recently, new interest in them has come from the investigation of the so-called "L-space conjecture", that predicts that Heegaard Floer L-spaces can be characterised as those 3-manifolds that do not admit coorientable taut foliations. A possible approach to the study of this conjecture is analysing surgeries on knots and links. Most of the techniques employed for constructing taut foliations on Dehn surgeries usually make use of some property of the exterior of the link, for example its fiberedness.

On an Eichler-Shimura decomposition for ordinary p-adic Siegel modular forms (live stream)

There are two different ways to construct families of ordinary p-adic Siegel modular forms. One is by p-adically interpolating classes in Betti cohomology, first introduced by Hida and then given a more representation-theoretic interpretation by Emerton. The other is by p-adically interpolating classes in coherent cohomology, once again pioneered by Hida and generalised in recent years by Boxer and Pilloni. I will explain these two constructions and then discuss joint work in progress with James Newton and Juan Esteban Rodríguez Camargo that aims to compare them.

The purpose of this talk is to survey Gerd Faltings’s contributions to the Arakelov geometry of curves. The groundwork was laid in his paper “Calculus on arithmetic surfaces”, finished in early 1983, and published in Annals in 1984. As Faltings writes in the introduction, the results of this paper turned out to be “extremely useful” to the author in finding his proof, in May 1983, of the Mordell conjecture. We present some of the fundamental ideas from loc. cit., and then proceed to discuss recent developments related to its contents.

The Oberseminar is a very long running seminar at MPI (‘Ober‘ standing for 'upper'). Its idea is that the guests of the MPI speak in this seminar (hopefully early in their stay) and get the chance to explain their work to the other guests.
