In memory of Jesús Begoña Aina, excellent teacher and person, whom we used to call affectionately “El Lennon”

We say that a subset of \({\mathbb {R}}^n\)



The author thanks J. F. Fernando for a careful reading of this article and his valuable suggestions on improving it. Some of the images were obtained using the software Surfer (, which was brought to the author’s attention by Gaël Cousin.

This work was developed during a one-year research stay at the Department of Mathematics of the Università di Pisa (D.R. no 27519 of 29/07/2013, MAT/03).
