Chern Classes

Play an AI-generated podcast conversation about this lesson

What are Chern classes and in which branches of mathematics and physics are they fundamental concepts?

Chern classes are characteristic classes associated with complex vector bundles. They are fundamental concepts in algebraic topology, differential geometry, algebraic geometry, string theory, Chern-Simons theory, knot theory, and Gromov-Witten invariants.

Who introduced Chern classes and in which year?

Shiing-Shen Chern introduced Chern classes in 1946.

What is the purpose of Chern classes in distinguishing between vector bundles?

Chern classes provide a simple test to determine if two vector bundles are different. If the Chern classes of a pair of vector bundles do not agree, then the vector bundles are different.

Is the converse of the test provided by Chern classes true?
