Math. 89 (2015), 771-7830001-9054http://repozytorium.ur.edu.pl/handle/item/1286We prove that the superstability of some functional equations (e.g., of Cauchy, d’Alembert, Wilson, Reynolds, and homogeneity) is a consequences of two simple theorems. In this way we generalize several classical superstability results.engSuperstabilityfunctional equationarticle
