Adams' operation and the symbol for the normed residue

  • 28 Accesses


We study the possibility of a meaningful extension of the ring of cohomologies of a point using algebraic extensions of local fields. It appears that complex K-theory is a good model problem for this. We prove that the effect of the Adams operation on the cohomologies of a point in extended K-theory coincides with the symbol for the local Artin reciprocity law. K-theories contained in a fixed K-theory with extended ring of cohomologies of a point are defined by higher branching groups.
