Abstract

In this paper, we obtain some results on the m-variable cubic functional equation \[f(2x_1 + y_1,..., 2x_m + y_m) + f(2x_1 - y_1,..., 2x_m - y_m)\\ = 2f(x_1 + y_1,..., x_m + y_m) + 2f(x_1 - y_1,..., x_m - y_m) + 12f(x_1,..., x_m).\] The cubic form \(f(x_1,..., x_m) = \sum_{1\leq i\leq j\leq k\leq m} a_{ijk}x_ix_jx_k\) is a solution of the above functional equation.
