Zero sets of Lie algebras of analytic vector fields on real and complex 2-dimensional manifolds, II

Morris W. Hirsch, F. -J. Turiel

On a real ($\mathbb{F}=\mathbb{R}$) or complex ($\mathbb{F}=\mathbb{C}$) analytic connected 2-manifold $M$ with empty boundary consider two vector fields $X,Y$. We say that $Y$ {\it tr…
