CR Yau finite-generation conjecture for Sasakian manifolds

Let $M$ be a complete noncompact Sasakian $(2n+1)$-manifold with nonnegative pseudohermitian bisectional curvature, and let $\mathcal{O}_p^{CR}(M)$ denote the ring of all CR-holomorphic functions on $M$ of polynomial growth. CR Yau finite-generation conjecture. The ring $\mathcal{O}_p^{CR}(M)$ is finitely generated. This is presented as the second CR Yau uniformization conjecture, following the stated dimension estimate for CR-holomorphic functions; no resolution is given in the supplied text.
