Course Objective

The purpose of this course is to give an introduction to the classical Chern-Weil theory of characteristic classes with real coefficients. We define a singular cohomology class which turns out to be a differential topological invariant for a topological vector bundle.

Learning Outcomes of the Course Unit

1   will be able to know Chern-Weil theory
2   will be able to know characteristic classes
3   will be able to vector bundles
4   will be able to compute topological invariants of vector bundles and principle bundles in terms of connections and curvatures
5   will be able to explain the relation between theory of chracteristic classes and cohomology groups of BG
