This is the third version of a book on differential manifolds. The first version appeared in 1962, and was written at the very beginning of a period of great ex
A first approximation to the idea of a foliation is a dynamical system, and the resulting decomposition of a domain by its trajectories. This is an idea that da
This monograph is based on the author's results on the Riemannian ge ometry of foliations with nonnegative mixed curvature and on the geometry of sub manifolds
