Resolubilidade local para duas classes de campos de vetores suaves complexos
Resumen
This work study complex linear partial differential operators of order one without
having terms of zero order (complex vector fields). We have established a necessary and
suficient condition for local solvability of a class of operators which are not elliptic precisely
in a 1-dimensional submanifold and we construct solutions for a class of operators satisfying
the condition (P) and which are not elliptic precisely in a point.
