Quasiregular Mappings

Quasiregular Mappings extend quasiconformal theory to thenoninjective case.They give a natural and beautifulgeneralization of the geometric aspects ofthe theory ofanalytic functions of one complex variable to Euclideann-space or, more generally, to Riemannian n-manifolds. Thisbook is a self-contained exposition of the subject. A braodspectrum of results of both analytic and geometric characterare presented, and the methods vary accordingly. The maintools are the variational integral method and t
