Top-degree solvability for hypocomplex structures and the cohomology of left-invariant involutive structures on compact Lie groups
We use the theory of dual of Fréchet-Schwartz (DFS) spaces to establish a sufficient condition for top-degree solvability for the differential complex associated to a hypocomplex locally integrable structure. As an application, we show that the top-degree cohomology of left-invariant hypocomplex str...
