Löwner chains with complex leading coefficient



In this paper we confirm that several crucial theorems due to Pommerenke and Becker for the theory of Löwner chains work well without normalization on the complex-valued first coefficient. As applications of those considerations, some new univalent and quasiconformal extension criteria are given in the last section.
