Integral conditions in the theory of the Beltrami equations

arXiv:1001.2821

Abstract

It is shown that many recent and new results on the existence of ACL homeomorphic (and more strong) solutions for the Beltrami equations with integral constraints follow from our extension of the well--known Lehto existence theorem.
