Abstract
We study singular hyperkähler quotients of the cotangent bundle of a complex semisimple Lie group as stratified spaces whose strata are hyperkähler. We focus on one particular case where the stratification satisfies the frontier condition and the partial order on the set of strata can be described explicitly by Lie theoretic data.

This erratum concerns the K��hler potential F defined in the second displayed equation of [M, Sect. 4.2], which is incorrectly claimed to be proper.
