Based on a Harvard University course, this graduate textbook explains the theory of quasiconformal mappings, explores solutions of the Beltramu equation, and describes the properties of Techimuller space. Originally published in 1966 by Van Nostrand, the second edition adds closing contributions on new developments in Teichmuller theory, complex dynamics, and hyperbolic structures on three-manifolds.
