| Global Nonlinear Stability of Minkowski Space for the Massless Einstein--Vlasov System |
| Speaker: | Martin Taylor (Cambridge, UK) |
| Abstract: | Massless collisionless matter is described in general relativity by the massless Einstein–Vlasov system. I will present a proof that for smooth asymptotically flat Cauchy data for this system which is sufficiently close, in a suitable sense, to the trivial solution, Minkowski space, the resulting maximal development exists globally in time and asymptotically decays appropriately. By appealing to the corresponding result for the vacuum Einstein equations, a monumental result first obtained by Christodoulou–Klainerman in the early ’90s, theproof reduces to a semi-global problem. A key step is to estimate certain Jacobi fields on the mass shell, a submanifold of the tangent bundle of the spacetime endowed with the Sasaki metric. |

| Nocommutative Geometry, Spectral Action and the Higgs |
| Speaker: | Fedele Lizzi (University of Naples) |
| Abstract: | Im Rahmen des Seminars für Mathematische Physik: A pedagogical introduction to the noncommutative geomentry from the
spectral point of view, and its applications to the standard model of
fundamental interactions will be given. I will discuss how the SM can
be seen as a noncommutative geometry, described by the spectra of
operators, and how the Higgs field emerges naturally on a par with
the other bosons. I will also discuss the attempts to confront the
model with experiments and its possible predictive power.
