We examine the general problem of computing characteristic invariants of principal bundles whose structural group [italic capital]G is a topological group. Unde

This work develops a topological analogue of the classical Chern-Weil theory as a method for computing the characteristic classes of principal bundles whose str

The theory of characteristic classes provides a meeting ground for the various disciplines of differential topology, differential and algebraic geometry, cohomo

This monograph is based on lectures on topological quantum field theory given in 1989 at Princeton University by E. Witten, in which he unified several importan

Characteristic classes are central to the modern study of the topology and geometry of manifolds. They were first introduced in topology, where, for instance, t
