covariant quantum spaces, focusing on the fuzzy 4-sphere. These spaces realize quantum geometries with local and global symmetries. The fluctuations on such a background within the IKKT matrix model lead to a higher spin theory, due to the underlying twisted bundle structure. Some aspects of the gravitational sector are elaborated, and the linearized Einstein equations modified by an IR cutoff are extracted under some assumptions.]]>

Walter Thirring (29 April 1927 - 18 August 2014) was one of Austria’s most distinguished physicists during his long professional career. He made seminal contributions to many areas of physics and was a pioneer of modern

mathematical physics. He was the founding president and first director of the Erwin Schrödinger Institute for Mathematical Physics. This symposium is dedicated to the memory and scientific legacy of Walter Thirring.

Morawetz type estimate that is stronger than the one assumed in previous work, without passing through the scalar wave equation on the Yang-Mills curvature, using the Yang-Mills equations directly.]]>

The talk will be based on the recent preprint https://arxiv.org/abs/1701.07804]]>

nanoscale, e.g. molecular dynamics. This presentation will explore opportunities from coarsegrained simulations. Spatial coarse-graining leads to model structures that capture some complex experimental features, such as nanopore distribution, correlations from scattering experiments, and mechanical indentation moduli. Temporal coarse-graining then is proposed in the framework of Transition State Theory and Kinetic Monte Carlo, where both the chemical environment and the mechanical interactions determine the mesostructural evolution of the material. First results on predicted hydration rate of cement hydrates will be discussed, as well as implications for other mesostructured engineering materials such as zeolites and rubber-based tyre compounds.

I will explain the basic construction of Newton-Cartan gravity plus some of its

generalizations thereby putting an emphasis on how these different theories

can be obtained by taking limits or reductions of General Relativity.]]>
