Department of Mathematics, Urmia University, P.O.Box 165, Urmia, Iran.


In this paper, we investigate the Hyers-Ulam stability for the system of additive, quadratic, cubic and quartic functional equations with constants coefficients in the sense of dectic mappings in non-Archimedean normed spaces.
