Abstract

In this paper we discuss some properties concerning sets of constant width and some related classes of sets. In particular, we discuss for such sets radii, self radii, and the existence of centers and incenters. By means of several examples, some of them rather pathological, we try to sketch a fairly complete picture concerning the different situations that are possible and their implications.
