In mathematics, the Riesz–Thorin theorem, often referred to as the Riesz–Thorin interpolation theorem or the Riesz–Thorin convexity theorem, is a result about interpolation of operators. It is named after Marcel Riesz and his student G. Olof Thorin. This theorem bounds the norms of linear maps acting … See more First we need the following definition: Definition. Let p0, p1 be two numbers such that 0 < p0 < p1 ≤ ∞. Then for 0 < θ < 1 define pθ by: 1/pθ = 1 − θ/p0 + θ/p1. By splitting up the function f in L as the product f = f f … See more We will first prove the result for simple functions and eventually show how the argument can be extended by density to all measurable functions. See more Hausdorff–Young inequality It has been shown in the first section that the Fourier transform $${\displaystyle {\mathcal {F}}}$$ maps … See more There are several ways to state the Riesz–Thorin interpolation theorem; to be consistent with the notations in the previous section, we shall use the sumset formulation.

In fact, … See more While the Riesz–Thorin interpolation theorem and its variants are powerful tools that yield a clean estimate on the interpolated … See more B.
