Scalar curvature along Ebin geodesics

Christoph Böhm (Münster)

Let \(M^n\) be a smooth, compact manifold and let \(N\) denote the set of Riemannian metrics on \(M^n\) with a fixed smooth volume density \(\mu\) of volume 1. For any \(g_0 \in N\) , we show that...

The Chern-Gauss-Bonnet theorem on semi-Riemannian manifolds

Marten Steuer (UP)

The Chern-Gauss-Bonnet theorem is one of the most fundamental results in Riemannian geometry, which connects the geometry of a compact, oriented Riemannian manifold \( (M,g)\) with its topology. For...

Malliavin calculus in regularity structures

Lucas Broux (MPIMS, Leipzig) (online)

This talk will be concerned with some aspects of the renormalization of the \( \Phi^4\) stochastic partial differential equation, in the singular but subcritical (also called super-renormalizable)...

Order and Number: the causal set approach to quantum gravity

Sumati Surya (Raman Research Institute, Bengalore)

In this talk I will sketch in broad lines a proposal for quantum space time, which is built purely on discrete, order theoretic principles. A key motivation is the Lorentzian character of spacetime,...
