Abstract

Let X be a two-dimensional, conected, smooth manifold and let L be a nonsingular complex vector field, with smooth coefficients, defined on X. This project deals with the study of problems related to global and semiglobal solvabitity of equations in the form Lu=Au+f defined in X, where A and f are smooth functions. Also, this project deals with the Riemann-Hilbert problem with equationLu=Au+B\overline{u}+f, em U\subset R^2with the boundary condition\Re(gu)=h, on \partial U,where L is a smooth complex vector field defined on R^2, f\in C^\infty(R^2),g\in C^\alpha(\partial U, S^1) andh\in C^\alpha(\partial U, R).
