| Abstract: |
| In this paper, we investigate the structure of the equation over finite fields with n unknowns and with degree n which vanish only at zero. By using the factorization of the irreducible multivariable polynomial in some extension field and with the Chevalley Theorem, a su-cient and necessary condition of the equation with n unknowns and with degree n which vanish only at zero is obtained. Furthermore, we construct some explicit equations of this class. |
