Abstract
Inflation is the most compelling proposal which explains the fine-tuning of the initial conditions of the Universe's history and also gives rise to the primordial density perturbations that source the formation of galaxies and galaxy clusters. Observations suggest that the Universe is engaging at present in a late inflation period, driven by some exot ...

ASTRONOMY

From the beginning of time, humankind has wondered what lies behind the darkness of the night sky. From the pre-telescope era to the present, our ability to see the lowest surface brightness details in the sky has improved by a factor of one million. In this talk, I describe how our vision of the sky has changed over time and how the recent developments in ultra-deep imaging have speed up our capacity to discover new objects and structures in the sky. ...

Rapoport-Zink Spaces for Local P-shtukas

School
MATHEMATICS

Rapoport-Zink spaces for p-divisible groups are local counterparts for Shimura varieties. According to the dictionary between function fields and number fields, they correspond to the RZ-spaces for local P-shtukas. We review the construction of these moduli spaces and then discuss our approach for computing the semi-simple trace of Frobenius on their (nearby-cycles) cohomology.
