Galois representations attached to elliptic curves and Serre's uniformity question.

The study of Galois representations attached to elliptic curves is a very fruitful branch of number theory, leading to the solution of very difficult problems, such as Fermat’s Last Theorem. Given an ...

Courant's nodal domain theorem and Steklov eigenfunctions

The classical Courant's nodal domain theorem states that the n-th eigenfunction of the Laplacian on a compact manifold has at most n nodal domains. The same holds for Steklov eigenfunctions on a compa...

Scalar curvature and surgery, II

We will study the behaviour of lower scalar curvature bounds under local deformations of the underlying Riemannian metrics. A major application is the preservation of positive scalar curvature metrics...

Scalar curvature and surgery, I

We will study the behaviour of lower scalar curvature bounds under local deformations of the underlying Riemannian metrics. A major application is the preservation of positive scalar curvature metrics...

Minimal model program for Mgbar

We will survey developments in the minimal model program for Mgbar over the last 15 years. After summarizing various strategies to determine moduli interpretations of the log canonical models of Mgba...

Holomorphic graded-local conformal nets and vertex operator superalgebras

In the recent work arXiv:2303.17190v2, G. Höhn and S. Möller propose a classification of vertex operator superalgebras (VOSAs) with central charge at most 24 and with trivial representation theory. VO...

Positive scalar curvature with point singularities

I will explain a certain topological construction of positive scalar curvature metrics with uniformly Euclidean \(L^{\infty}\) point singularities. This provides counterexamples to a conjecture of Sch...

Generalized Killing spinors and applications to General Relativity

In Special Relativity, the vanishing of mass occurs exclusively in the cases of vacuum and radiation. In this talk, we demonstrate that an analogous result holds within the framework of General Relati...

On the positive mass problem for initial data with a positive cosmological constant

The concept of mass for time-symmetric initial data has been extensively explored and is now a cornerstone in the study of contemporary Mathematical General Relativity, especially in relation to space...

Orbifold singularity formation along ancient and immortal Ricci flows

With Alix Deruelle, we explain how Ricci flow develops or resolves 4-dimensional orbifold singularities by a notion of stability depending only on the curvature at the singular points. We construct a ...
