Sažetak

We will establish stability of Fréchet functional equation
$$\Delta_{x_1, \dots, x_n}^nf(y)= 0$$ in non-Archimedean normed spaces for some unbounded control function. Among some applications of our results, we will give a counterexample to show that the nature of stability in non-Archimedean normed spaces is different from one in classical normed spaces.
