Riassunto:

This book is an extensive study of the theory of homogenization of partial differential equations. This theory has become increasingly important in the last two decades and it forms the basis for numerous branches of physics like the mechanics of composite and perforated materials, filtration and disperse media. It will become an indispensable reference for graduate students in mathematics, physics and engineering.
