## Abstract Let __A~t~f__(__x__) denote the mean of __f__ over a sphere of radius __t__ and center __x__. We prove sharp estimates for the maximal function __M~E~ f__(__X__) = sup~t~β~__E__~ |A__tf__(x)| where __E__ is a fixed set in IR^+^ and __f__ is a radial function β __L__^__p__^(IR^__d__^). L

## Abstract We consider Sobolev embeddings between Sobolev and Besov spaces of radial functions on noncompact symmetric spaces of rank one. An asymptotic behaviour of entropy numbers of the compact embeddings is described. The estimates are used for investigation of the negative spectrum of SchrΓΆdi
Matrix representations of Hecke operators on classical holomorphical cusp forms and the corresponding period polynomials are well known. In this article we derive representations of Hecke operators for vector-valued period functions for the congruence subgroups Ξ 0 (n). For this we use an integral t
