Abstract: Let $ (X,\,\phi )$ be a locally compact dynamical system, and $ {{\mathbf{Z}}^ + }{ \times _\phi }\,{C_0}(X)$ the norm-closed subalgebra of the crossed product $ Z{ \times _\phi }{C_0}(X)$ generated by the nonnegative powers of $ \phi $ in case $ \phi $ is a homeomorphism. If $ \phi $ is just a continuous map, $ {{\mathbf{Z}}^ + }{ \times _\phi }{C_0}$ can still be defined by a crossed product type construction. The ideal structure of these algebras is determined in case $ \phi $ acts freely. A class of strictly transitive Banach modules is described, indicating that for the nonselfadjoint operator algebras considered here, not all irreducible representations are on Hilbert space. Finally in a special case, the family of all invariant maximal right ideals is given.
