The non-minimal coupling to gravity renders heavy the Affleck-Dine field during inflation and avoids the generation of isocurvature fluctuations. During the subsequent kinetic era the Ricci scalar changes sign and the effective mass term of the Affleck-Dine field becom ... 16:00 - 17:00 Mathematics Colloquium Shtukas and the Analogy Between Number Fields and Function Fields School MATHEMATICS During the last decades lots of efforts have been invested in developing A. Weil's discourse on the analogy in mathematics. This method essentially aims to bring number theory into the light of geometry, through a bridge called the arithmetic of function fields. In this context, and as it may be observed through Langlands philosophy, moduli spaces (/stacks) for global G-shtukas appear as analogs for Shimura varieties, and consequently, they play a crucial role in Langlands program over function fields. They possess local counterparts which are called Rapoport-Zink spaces for local P-shtukas (i.e. function fields analogs for Rapoport-Zink sp ... 16:00 - 17:00 Mathematics Colloquium Shtukas and the Analogy Between Number Fields and Function Fields School MATHEMATICS During the last decades lots of efforts have been invested in developing A.
