Stein interpolation for the real interpolation method

Functional Analysis 2022-03-16 v2

Abstract

We prove a complex formulation of the real interpolation method, showing that the real and complex interpolation methods are not inherently real or complex. Using this complex formulation, we prove Stein interpolation for the real interpolation method. We apply this theorem to interpolate weighted LpL^p-spaces and the sectoriality of closed operators with the real interpolation method.
