I received the following answer, which is just what I'm looking for: Date: Mon, 17 Aug 92 21:08:24 +0200 From: Torsten Ekedahl <teke@matematik.su.se> Message-Id: <9208171908.AA11751@candida.matematik.su.se> To: victor@watson.ibm.com In-Reply-To: victor@watson.ibm.com's message of Mon, 17 Aug 1992 15:47:12 GMT Subject: The character group of k((x)) Andre Weils Basic Number Theory (Springer Grundl d. math. Wiss. 144), particularly II:5, discusses this. Indeed, k((x)) is self dual as topological dual, k[[x]] is a compact subgroup with discrete quotient and is its own annihilator for a suitable normalisation of the self duality. -- Victor S.
