Correction to: Annales mathématiques du Québec https://doi.org/10.1007/s40316-020-00140-8 The purpose of this note is to clarify the relation between the content of our paper [4] and the results present in the literature. As we learned after [4] has been published electronically, the main result in our paper has already appeared in Lemma 2 in [1] as well as, in a slightly different form, in Lemma 2.6 in [3] and also in a Remark following Lemma 6.3 in [2]. There are two steps in proving that (n − 1) Steiner symmetrizations can transform an ellipsoid to a ball. The first one is to show that a Steiner symmetrization transforms an ellipsoid into an ellipsoid. We prove this by making use of the classical Blaschke–Santaló inequality, and this argument does not appear in the references. The second step is to apply successive symmetrizations to end up with a ball. We first show the existence of the desired directions and then give an explicit algorithm for this second part. The second step was outlined in [1]. We thank Professor Burchard who, after the publication of [4], drew our attention to the relevant literature.
