Outline of Final Research Achievements

We studied a geometric realization of the local Langlands correspondence.
More concretely, we constructed affinoids in the Lubin-Tate perfectoid space, which is a limit space of Lubin-Tate spaces, using CM points and showed that the etale cohomology of the reductions of formal models of the affinoids realizes the local Langlands correspondence and the local Jacquet-Langlands correspondence for simple supercuspidal representations.
