WebThe proofs of the Poincar´e duality theorem, the Thom isomorphism theorem, and of the Leray-Hirsch theorem. The beautiful work of J.P. Serre on the cohomology of loops spaces, Serre classes of Abelian groups and their applications to homotopy theory. The first topic ought to be part of a first year graduate course in algebraic topology, and ... Webfollowed by the definition of K-theory and proofs of the most important theorems in the subject, such as the Bott periodicity theorem and the Thom isomorphism theorem. The multiplicative structure of K-theory and the Adams operations are also discussed and the final chapter details the construction and computation of characteristic classes.
