As part of his celebrated Complex Frobenius Theorem, Nirenberg showed that given a smooth elliptic structure (on a smooth manifold), the manifold is locally diffeomorphic to an open subset of R r× C n (for some r and n) in such a way that the structure is locally the span of∂∂ t 1,…,∂∂ t r,∂∂ z‾ 1,…,∂∂ z‾ n; where R r× C n has coordinates (t 1,…, t r, z 1,…, z n). In this paper, we give optimal regularity for the coordinate charts which achieve this realization. Namely, if the manifold has Zygmund regularity of order s+ 2 and the structure has Zygmund regularity of order s+ 1 (for some s> 0), then the coordinate charts may be taken to have Zygmund regularity of order s+ 2. We do this by generalizing Malgrange's proof of the Newlander-Nirenberg Theorem to this setting.
