Abstract

The paper is devoted to prove maximum principles for the certain functionals defined on solution of the fourth order nonlinear elliptic equations. These maximum principle so obtained is used to prove the nonexistence of nontrivial solutions of the fourth order nonlinear elliptic equation with some zero boundary conditions.
