Abstract
Let H be a Hopf algebra and M a representation or a corepresentation of H. In this paper we study semiinvariants of M. This notion generalizes the known concept of weight spaces in the context of representations of Lie algebras. Our best results are attained for pointed Hopf algebras, and semiinvariants which are related to the coradical filtration of H.
