Abstract | |
Let F : R(2) -> R(2), F = (p, q), he a polynomial mapping such that, det DF never vanishes. In this paper in is shown that if either p or q has degree less or equal 3, then F is injective. The technique relates solvability of appropriate vector fields with injectivity of the mapping. (AU) | |
