%X Some remarks about the coherence of the stability of several functional equations with topology of their target spaces are given. The equations in question are: homogeneity (first of all) and quadratic ones, as well as those of Drygas, Jensen and Schr der. Moreover, we prove, by method different than those used in earlier papers, the superstability of the following equations: Dhombres¡¯, Lobachevski¡¯s and Mikusi¨½ski¡¯s ones and those of cosine, sine and of homomorphisms.
