报告摘要:Vector bundle, roughly speaking a bunch of vector spaces, is one of the most fundamental objects in topology, geometry and physics. Characteristic classes are the basic topological invariants for vector bundles, which have numerous applications. In the lecture, we will briefly introduce the Chern classes, Pontryajin classes and Thom classes, Euler classes for different kinds of vector bundles. The reference books for our lectures are (1) "Characteristic Classes" by Milnor; (2) "Differential forms in algebraic topology" by Bott and Tu;  (3) "Chern-Weil theory and Witten deformation" by Weiping Zhang.
