چكيده فارسي :
In this paper we introduce Banach ternary modules over Banach ternary algebras and using
fixed point methods, we prove the stability of ternary additive, quadratic, cubic and quartic
derivations in such modules for the functional equation
[(f(ax + y) + f(ax − y) = a^{m−2}[f(x + y) + f(x − y)$
+ 2(a2 − 1)[am−2f(x) +

f(y)].
for each m = 1, 2, 3, 4.
