Abstract
Given an infinite, compact, monothetic group we study decompositions and structure of unbounded derivations in a crossed product C-algebra obtained from a translation on by a generator of a dense cyclic subgroup. We also study derivations in a Toeplitz extension of the crossed product and the question whether unbounded derivations can be lifted from one algebra to the other.
