this website is describe the chern classes and The Newstead-Ramanan conjecture for Chern classes.
The Chern classes of a complex manifold are the Chern classes of its tangent bundle. The ith Chern class is anobstruction to the existence of (n-i+1) everywhere complex linearly independent vector fields on that vector bundle. The ith Chern class is in the (2i)th cohomology group of the base space.in topology, differential geometry, and algebraic geometry, it is often of vital importance to know how many linearly independent sections a vector bundle has. The Chern classes can be used to provide a great deal of information in answering this question
