I am looking an introductory book on "quasiconformal mappings" for self-study. Also I would like to know about motivation and history behind this concept (I am a beginner of this subject).

I really appreciate any help you can provide.

A standard reference for quasiconformal mappings in $\mathbb{C}$ is Lehto/Virtanen, "Quasiconformal Mappings in the Plane" - containing also quite some historical references. For the higher-dimensional theory of quasiconformal mappings, I'd refer to Väisälä's book "Lectures on $n$-Dimensinonal Quasiconformal Mappings". More a modern approach via PDEs, the book "Elliptic PDEs and Quasiconformal Mappings in the Plane" of Astala et. al. is the right source for your self-study, containing a lot of historical remarks as well.


Use Lectures on Quasiconformal Mappings by Ahlfors. The second edition is TeX-ed and has some survey articles attached to it which are more advanced than the main text, but give an insight into how quasiconformal maps are used in complex dynamics and hyperbolic geometry. The motivation and history is a part of what you'll learn reading that book.

  • $\begingroup$ I looked at your link and it seems like a very good book. Thank you very much. Is there any good online source about history of quasiconformal mappings? $\endgroup$

    $\begingroup$ The few paragraphs that Ahlfors spends on the history and motivation are enough for me. There is a survey by Lehto but it's paywalled and I never read it. $\endgroup$

Just to complement the above answers, I think that the book by Fletcher and Markovic "Quasiconformal Maps and Teichmüller Theory" is pretty nice introductory reference to this topic as well. Another book that you should look at is Hubbard's "Teichmüller Theory Vol.1"; the exposition of q.c. mappings in Chapter 4 is beautifully written.
