Material

Here you will find some relevant study material such as lecture notes and links to literature.

A comprehensive treatment of the subject is the monograph Elliptic partial differential equations and quasiconformal mappings in the plane by K. Astala, T. Iwaniec and G. Martin (link to e-book accessible from HY network). Parts of Chapters 1-5 are relevant for this course.
