"The classical theory of dynamical systems has been greatly generalized to the rich context of foliations and actions of groups and pseudogroups on spaces. The book under review expounds on this theory in considerable detail... Much of the material in this book is pertinent to applied mathematics... Experts in control systems also recognize foliation theory as a cognate subject of some interest... With the phenomenal interaction between pure and applied mathematics over recent decades, this book should be of considerable interest to many application-oriented mathematicians." -SIAM Book Reviews
