Implications for Non-indexical Casesthe characteristic classes of the normal bundle. Moreover, the cohomology classes have formal properties analogous to those of the characteristic classes of a vector bundle. Hence, it is reasonable to try to obtain them by mapping into a classifying space for foliations, that is, some sort of foliat

Prolongations, Connections, and Characteristic Classes,s extend to give new kinds of characteristic classes associated to a foliation. The presentation of the material will not be at all standard, however. Indeed, the same characteristic classes associated to a foliation of codimension . can be obtained from the algebra of formal power series vector fie

Book 1983 some subgroup G of GL(V). It is particularly pleasant if one can choose the coordinate systems so that the Jacobian matrices of the coordinate transformations belong to G. A reduction to G is called a G-structure, which is called integrable (or flat) if the condition on the Jacobians is satisfied.
