Spectral analysis and mean-periodic functions on rank one symmetric spaces. (English) Zbl 0652.22012

Let X be a symmetric space of rank one and of noncompact type. The manifold X can be represented as a homogeneous space \(X=G/K\), where G is a semisimple noncompact Lie group of finite center and K is a maximal compact subgroup of G. The action of G on the space E(X) of smooth functions with the usual Fréchet topology is defined by the formula: \(L_ gf(x):=f(g^{-1}x)\). The subject of the present paper is the spectral analysis and synthesis in E(X) with respect to the family \(e_{\lambda,b}\) of plane waves on X.
