To every solution of an elliptic PDE there corresponds a quasiharmonic field F = [B, E]a pair of vector fields with div B = 0 and curl E = 0 which are coupled by a distortion inequality. Quasiharmonic fields capture all the analytic spirit of quasiconformal mappings in the complex plane. Among the m
