Аннотация:
Perverse sheaves on complex algebraic varieties have some
remarkable rigidity properties. When translated through the
Riemann-Hilbert correspondence, these can often (e.g., via the
theory of Hodge modules) lead to highly non-trivial vanishing
theorems on the cohomology of coherent sheaves. I'll explain ongoing
work (joint with Jacob Lurie) on a Riemann-Hilbert functor for
perverse sheaves on algebraic varieties over a p-adic field. When
applied to $Q_p$-sheaves, this allows us to recover some of the
aforementioned vanishing theorems. Moreover, unlike the complex
variant, our functor also makes sense for $F_p$-sheaves, which leads
to new vanishing theorems in mixed characteristic algebraic
geometry.
