This mistake in [B-X] was first noted by Chai in [1], Remark 4.8 (2). Chai then notes that he was informed by Bosch that the mistake does not affect any other subsequent results in [B-X]. Our aim in this note is to carefully go through the proof of Proposition 1.8 in [2] and detail what results of [B-X] we use, so that the careful reader will be convinced that the proof of Proposition 1.8 is complete, and is not affected by the mistake in [B-X]. The comments on our original proof are in italic.

Chevalley's ambiguous class number formula for an arbitrary torus
This version is a significant improvement of the original paper. It includes a new section where we discuss norm tori in some detail. The new abstract is the following: In this paper we obtain…
Néron models, Lie algebras, and reduction of curves of genus one
Let K be a discrete valuation field. Let OK denote the ring of integers of K , and let k be the residue field of OK , of characteristic p ≥ 0. Let S := SpecOK . Let X K be a smooth geometrically…
Cohomological Interpretation of the Motivic Zeta Function
In this chapter, we assume that k is algebraically closed. We will show how the motivic zeta function of a tamely ramified semi-abelian K-variety admits a cohomological interpretation by means of a…
Cokernels in the Category of Formal Group Laws
In a recent article, the authors established an explicit description of kernels in the category of the formal group laws over the ring of Witt vectors over a finite field in terms of Fontaine’s…
Models of Curves and Wild Ramification
Let K be a complete discrete valuation field with ring of integers OK and residue field k of characteristic p ≥ 0, assumed to be algebraically closed. Let X/K denote a smooth proper geometrically…
Fibrations with few rational points
We study the problem of counting the number of varieties in families which have a rational point. We give conditions on the singular fibres that force very few of the varieties in the family to…
Wild models of curves
Let K be a complete discrete valuation field with ring of integers OK and algebraically closed residue field k of characteristic p > 0. Let X/K be a smooth proper geometrically connected curve of…
REDUCTION IN THE CASE OF IMPERFECT RESIDUE FIELDS
Let K be a complete field with a discrete valuation v, ring of integers OK , and maximal ideal (πK). Let k := OK/(πK) be the residue field, assumed to be separably closed of characteristic p ≥ 0.…
Trace formula for component groups of N\'eron models
We study a trace formula for tamely ramified abelian varieties $A$ over a complete discretely valued field, which expresses the Euler characteristic of the special fiber of the N\'eron model of $A$…

On the arithmetic of abelian varieties
In w 1 we consider the situation: L/K is a finite separable field extension, A is an abelian variety over L, and A, is the abelian variety over K obtained from A by restriction of scalars. We study…
Neron models for semiabelian varieties: Congruence and change of base field
Let O be a henselian discrete valuation ring with perfect residue field. Denote by K the fraction field of O = OK , and by p = pK the maximal ideal of O. Then every abelian variety A over K has a…
Intersection numbers of sections of elliptic surfaces
The theory of elliptic surfaces over C draws on ideas and techniques from arithmetic, geometry and analysis. Let f : X ~ S be a minimal elliptic fibration with non-constant j-invariant, which…
