Abstract
Let be the ring of integers in a finite extension of . If is a finite group and is a maximal -order containing the group ring , Jacobinski's conductor formula gives a complete description of the central conductor of into in terms of characters of . We prove a similar result for completed group algebras , where is a -adic Lie group of dimension 1. We will also discuss several consequences of this result.
