Abstract
We extend a classical theorem by H. Lewy to planar\sigma-{harmonic mappings, that is mappings U whose components u_1 and u_2 solve a divergence structure elliptic equation div(\nabla u ) = 0, for i = 1; 2. A similar result is established for pairs of solutions of certain second order non{divergence equations.File in questo prodotto:
