Milnor-Witt $K$-groups of local rings

Abstract

We introduce Milnor-Witt KK-groups of local rings and show that the nnth Milnor-Witt KK-group of a local ring RR which contains an infinite field of characteristic not 22 is the pull-back of the nnth power of the fundamental ideal in the Witt ring of RR and the nnth Milnor KK-group of RR over the nnth Milnor KK-group of RR modulo 22. This generalizes the work of Morel-Hopkins on Milnor-Witt KK-groups of fields.
