On non-abelian Lubin-Tate theory for GL(2) in the odd equal characteristic case

Abstract: In this paper, we define a family of affinoids in the tubular neighborhoods of CM points in the Lubin-Tate curve with suitable level structures, and compute the reductions of them in the equal characteristic case. By using etale cohomology theory of adic spaces due to Huber, we show that the cohomology of the reductions contributes to the cohomology of the Lubin-Tate curve. As an application, with the help of explicit descriptions of the local Langlands correspondence and the local Jacquet-Langlands correspondence due to Bushnell-Henniart via the theory of types, we prove the non-abelian Lubin-Tate theory for GL(2) in the odd equal characteristic case in a purely local manner. Conversely, if we admit the non-abelian Lubin-Tate theory, we can recover the explicit descriptions of the two correspondences geometrically.
