Abstract

The Poincaré compactification is an extension of a polynomial vector field to a compact manifold. We generalize this construction to weight-homogeneous vector fields with weight exponent \((1,\ell )\) and different weight-degrees. Then we apply this generalization of the Poincaré compactification to obtain new developments in the real Jacobian conjecture.
