Conference on "Interactions between higher algebra, manifolds and functor calculus", May 18-22, 2026

Functor calculus serves as a systematic method for approximating functors by their “polynomial” counterparts. These approximations often allow for interesting new computations in homotopy theory and geometry. For example, in the setting of manifolds, the work of Goodwillie–Klein–Weiss enables one to extend classical computations of spaces of embeddings beyond traditional stable ranges.

ChaBONNty conference, June 29 - July 3, 2026

The endeavor of provably computing rational points on curves stretches back millennia. In the last years the method of Chabauty and Coleman has seen major breakthroughs. The method itself has remarkable applications and currently there are several exciting generalisations being actively developed and applied. In addition to invited talks by established names in the field and an open problem session, we will offer speed talks to young researchers to advertise their work.

Conference on "New Perspectives on Stable Homotopy and Beyond", September 7-11, 2026

The goal of this conference is to bring together researchers working in and around stable and chromatic homotopy theory, higher categories, and their geometric counterparts. It will serve both to highlight recent advances in these fields and to celebrate the fundamental contributions of Neil Strickland to their development.

Program and Abstracts of MPIM Topology Seminar: Miniseries on topological modular forms and synthetic spectra
Topological modular forms (tmf) have long played a big role in modern homotopy theory, with applications ranging from studying bordism, to being a key part of the computation of stable homotopy groups of spheres. However, a complete computation of its homotopy groups has never appeared in the literature. 
 
In this mini-series, we will describe our approach to this computation using modern techniques in synthetic spectra and introducing a synthetic spectrum we call Synthetic modular forms (Smf).

MPIM Topology Seminar: Miniseries on topological modular forms and synthetic spectra
The previous two talks have covered why we want to compute the descent spectral sequence for Tmf, the definition of the synthetic spectrum Smf, and seen an array of tools to work with synthetic spectra. In this talk, the rubber hits the road and we use detection methods, synthetic generalisations of the Leibniz rule and Moss' convergence theorem, and a truncated version of the Burklund--Hahn--Senger omnibus theorem to fully calculate this spectral sequence. This finally gives all the details to this computation, which was started around 30 years ago by Hopkins and Mahowald.

You might think that non-noncommutative geometry is just geometry. But what kind, really? In other words, what is the geometry that is generalised in noncommutative geometry (NCG)? I will try to answer this by giving a (slightly fake) history of NCG as originating from a combination of C*-algebra theory, spectral geometry (hearing the shape of a drum), and some K-theory. Depending on the time, I might then sketch some cool theorems in NCG and applications in mathematics and physics.

I will carefully review the various equivalent definitions of principal $G$-bundles (free and proper $G$-action, fiber bundle with free and transitive $G$-action on fibers, local transition functions on cover satisfying cocycle condition, classifying map to $BG$). Then I show how these notions generalize to Lie $\infty$-groupoids. The main result is that we can still move between principal groupoid bibundles, anafunctors, and classifying maps in the $\infty$-categorical setting.

Working group on odd Khovanov homology

In this talk, I will discuss joint work with Sypropoulous and Vidyarthi in which we prove a conjecture of Migdail and Wehrli regarding the maps which odd Khovanov homology associates to knotted spheres. Our main tool is the spectral sequence from reduced OKH to Plane Floer homology.

In 1990, R. C. Baker and H. L. Montgomery conjectured that for almost all fundamental discriminants d, the derivative of the Dirichlet L-function associated to the quadratic character modulo d has around $\log\log |d|$ real zeros on the interval $[1/2, 1]$. Baker and Montgomery's motivation in studying these zeros stems from their connection to real zeros of Fekete polynomials and to sign changes of real character sums. In this talk I will present recent work that settles this conjecture (up to a small factor of $\log\log\log |d|$).
