Chern Class
A Gadget defined for Complex Vector Bundles. The Chern classesof a Complex Manifold are the Chern classes of its Tangent Bundle. The 
th Chernclass is an Obstruction to the existence of 
everywhere Complex linearly independentVector Fields on that Vector Bundle. The th Chern class is in the 
thcohomology group of the base Space.
