We hope that the tools and ideas presented here will serve as a basis for the study of more complex phenomena and problems."--Jacket.

This volume covers contemporary aspects of geometric measure theory with a focus on applications to partial differential equations, free boundary problems and w

The regularity theory of free boundaries flourished during the late 1970s and early 1980s and had a major impact in several areas of mathematics, mathematical p

This book is devoted to the Beltrami equations that play a significant role in Geometry, Analysis and Physics and, in particular, in the study of quasiconformal

This book is concerned with several elliptic and parabolic obstacle-type problems with a focus on the cases where the free and fixed boundaries meet. The result
