A -adic analogue of the Borel regulator and the Bloch-Kato exponential map

arXiv:math/0612611

Abstract

In this paper we define a -adic analogue of the Borel regulator for the -theory of -adic fields. The van Est isomorphism in the construction of the classical Borel regulator is replaced by the Lazard isomorphism. The main result relates this -adic regulator to the Bloch-Kato exponential and the Soulé regulator. On the way we give a new description of the Lazard isomorphism for certain formal groups.
