Riemannian Foliations (Progress In Mathematics),Used
Delivery time: 8-12 business days (International)
Foliation theory has its origins in the global analysis of solutions of ordinary differential equations: on an ndimensional manifold M, an [autonomous] differential equation is defined by a vector field X ; if this vector field has no singularities, then its trajectories form a par tition of M into curves, i.e. a foliation of codimension n 1. More generally, a foliation F of codimension q on M corresponds to a partition of M into immersed submanifolds [the leaves] of dimension ,, . p = n q. The first global image that comes to mind is 1; that of a stack of 'plaques'. 1; Viewed laterally [transver 11 sally], the leaves of such a 11 . stacking are the points of a 11 . quotient manifold W of di L..... ' _ mension q. ~) W M Actually, this image corresponds to an elementary type of folia tion, that one says is 'simple'. For an arbitrary foliation, it is only l u L ally [on a 'simpIe' open set U] that the foliation appears as a stack of plaques and admits a local quotient manifold. Globally, a leaf L may return and cut a simple open set U in several plaques, sometimes even an infinite number of plaques.
