Sub-Hermitian Geometry and the Quantitative Newlander-Nirenberg Theorem
Brian Street
Given a finite collection of complex vector fields on a manifold such that they and their complex conjugates span the complexified tangent space at every point, the…
Sharp Regularity for the Integrability of Elliptic Structures
Brian Street
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 ope…
Coordinates Adapted to Vector Fields III: Real Analyticity
Brian Street
Given a finite collection of vector fields on a manifold which span the tangent space at every point, we consider the question of when there is locally a coordinate sys…
