The theory of characteristic classes provides a meeting ground for the
various disciplines of differential topology, differential and algebraic
geometry, cohomology, and fiber bundle theory. As such, it is a
fundamental and an essential tool in the study of differentiable
manifolds.
In this volume, the authors provide a thorough introduction to
characteristic classes, with detailed studies of Stiefel-Whitney
classes, Chern classes, Pontrjagin classes, and the Euler class. Three
appendices cover the basics of cohomology theory and the differential
forms approach to characteristic classes, and provide an account of
Bernoulli numbers.
Based on lecture notes of John Milnor, which first appeared at Princeton
University in 1957 and have been widely studied by graduate students of
topology ever since, this published version has been completely revised
and corrected.
