Abstract:
In this work we consider a class of systems of two vector fields on the 3-torus associated to a closed smooth complex 1-form $c=a+ib$ with $b$ exact. Necessary conditions and sufficient conditions for this system to be globally solvable are provided in terms of the position of the global extrema and the connectedness of sublevel and superlevel sets of the primitives of $b$, together with arithmetical properties of the periods of $a$.References
