In this chapter, we shall explain basic properties of quasiconformal mappings which are needed in the later chapters. In Chapter 1, we have defined differentiable quasiconformal mappings. Here, we weaken the differentiability condition in the definition. Such a technical improvement allows us to use quasiconformal mappings as a tool in considerably more general situations, while formal treatment of such mappings remains the same as in the differentiable case.
