The Geisser-Levine method revisited, by Bruno Kahn

We reformulate part of the arguments of T. Geisser and M. Levine computing motivic cohomology with finite coefficients under the assumption that the Bloch-Kato conjecture holds. This reformulation amounts to a uniqueness theorem for motivic cohomology, and shows that the Geisser-Levine method can be applied generally to compare motivic cohomology with other types of cohomology theories.
