• K-theory of locally compact modules over rings of integers
  - Lemma 2.12 is false as stated. (and quite obviously so, the zero map is a counterexample!). This lemma is only used in the proof of Prop. 2.13. A correct proof is to observe that in the Minkowski embedding, if you use only a proper subset of the set of infinite places, you do not get a discrete embedding. And this is true because there is no discrete Z-lattice of rank n in a less than n-dimensional real vector space. That's all which is needed there. Lemma 2.12 was supposed to say something like that, but its weird wording misses what it was supposed to say and then got it all wrong.
