Abstract:
In this paper, we formulate axioms of certain graded cohomology theory and define higher Chern class maps following the method of Gillet [Gi1]. We will not include homotopy invariance nor purity in our axioms. It will turn out that the Riemann-Roch theorem without denominators holds for our higher Chern classes. We will give two applications of our Riemann-Roch results in $\S\S$11-13.
Keywords: $K$-theory, cohomology theory, Chern class, Riemann-Roch theorem.
