KAHW02 - Algebraic K-theory, motivic cohomology and motivic homotopy theory

Filtration by ramification groups of the Galois group of an
extension of local fields with possibly imperfect residue fields is defined
by Abbes and the speaker. The graded quotients are abelian groups and
annihilated by the residue characteristic. We discuss the main ingredients of
the proof and the construction of injections of the character groups of the
graded quotients.
