摘要 The Hopf's maximum principles are utilized to obtain maximum principles for functions defined on solutions of nonlinear elliptic equations in divergence form (g(u)u,i),i +f(x,u,q)=0(q=|△↓u|^2), subject The principles derived may be used to deduce bounds on the gradient q. The Hopf's maximum principles are utilized to obtain maximum principles for functions defined on solutions of nonlinear elliptic equations in divergence form (g(u)u,i),i +f(x,u,q)=0(q=|△↓u|^2), subject The principles derived may be used to deduce bounds on the gradient q.
