| چکیده | ||
| We show in this paper that a mapping $f$ satisfies the following functional equation \begin{eqnarray*} \biguplus_{x_2,\cdots,x_{d+1}}^{d}f(x_1) = 2^{d} \sum_{i=1}^{d+1}f(x_i), \end{eqnarray*} if and only if it is quadratic. In addition, we investigate generalized Hyers-Ulam stability problem for the equation, and thus obtain an asymptotic property of quadratic mappings as applications. | ||
