-adic geometry
arXiv:1712.03708
Abstract
We discuss recent developments in -adic geometry, ranging from foundational results such as the degeneration of the Hodge-to-de Rham spectral sequence for "compact -adic manifolds" over new period maps on moduli spaces of abelian varieties to applications to the local and global Langlands conjectures, and the construction of "universal" -adic cohomology theories. We finish with some speculations on how a theory that combines all primes , including the archimedean prime, might look like.
