Partial measures

We study sigma-additive set functions defined on a hereditary subclass of a sigma-algebra and taken values in the extended real line. Analogs of the Jordan decomposition theorem and the Radon-Nikodym theorem are obtained.Comment: 4 pages. Submitted to Lobachevskii Journal of Mathematics ( http://ljm.ksu.ru

Nikolskii inequality and functional classes on compact Lie groups

In this note we study Besov, Triebel-Lizorkin, Wiener, and Beurling function spaces on compact Lie groups. A major role in the analysis is played by the Nikolskii inequality.Comment: In this note (to appear in Funct. Anal. Appl.) we present results from our paper at arXiv:1403.3430 (to appear in Ann. Sc. Norm. Super. Pisa Cl. Sci.) in the simplified setting of compact Lie groups. We refer to the above paper for more general formulations in the setting of compact homogeneous manifolds and for the proof
