Abstract: We study conditions for a nonselfadjoint subalgebra of a von Neumann crossed product $ \mathcal{L}$ to be an algebra of analytic operators with respect to a flow on $ \mathcal{L}$. We restrict ourselves to the case where $ \mathcal{L}$ is constructed from a finite von Neumann algebra $ M$ with a trace preserving $ ^{\ast}$-automorphism $ \alpha $ that acts ergodically on the center of $ M$.
