• Ihe central theme rnnning through our investigation la the on-Laplacian operator in the plane. Upon multiplication by a suitable funetion we express it in divergence form, this allows os to speak of weak no-harmonir funetion jo 4/1,2 lo every no-harmonir function u we associate its conjogate funetion e. We focus our attention to Ihe first order Beltrami type equation for h u + iv.
