Abstract

The following problem of Markus and Yamabe is answered affirmatively: Let f be a local diffeomorphism of the euclidean plane whose jacobian matrix has negative trace everywhere. If f(0) = 0, is it true that 0 is a global attractor of the ODE dx/dt = f(x)? An old result of Olech states that this is equivalent to the question if such an f is injective. Here the problem is treated in the latter form by means of an investigation of the behaviour of f near infinity.

Keywords

Markus-Yamabe conjecture, asymptotic behaviour of solutions of ODE's, immersions, embeddings, injectivity of mappings, curve lifting, foliations
