Partial Fourier series on compact Lie groups

Analysis of PDEs 2021-07-02 v1

Abstract

In this note we investigate the partial Fourier series on a product of two compact Lie groups. We give necessary and sufficient conditions for a sequence of partial Fourier coefficients to define a smooth function or a distribution. As applications, we will study conditions for the global solvability of an evolution equation defined on T1×S3\mathbb{T}^1\times\mathbb{S}^3 and we will show that some properties of this evolution equation can be obtained from a constant coefficient equation.
