GENERAL EIGENVALUE PROBLEMS FOR QUASILINEAR ELLIPTIC SYSTEMS IN DIAGONAL FORM
对角形拟线性椭圆方程组的一般特征问题

In this paper, we consider a general eigenvalue problem for quasilinear elliptic systems: First, we get the bound of minimizing solutions for systems. Then, we apply the variational method to prove the existence of minimizing solutions for systems.
