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

This invaluable book is based on the notes of a graduate course on differential geometry which the author gave at the Nankai Institute of Mathematics. It consis

This book discusses topics ranging from traditional areas of topology, such as knot theory and the topology of manifolds, to areas such as differential and alge

A unique presentation of modern geometric methods in quantum field theory for researchers and graduate students in mathematics and physics.

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