the least action principle极小值原理
1.In this paper,existence theorems of solution for a class of semilinear elliptic equations-Δu=λ_1u-|u|~(2~*-2)u+g(x,u)+h(x),involving the critical Sobolev exponent 2~* and the first eigenvalue λ_1, has been given by ways of the least action principle and the orthogonal resolution on the Sobolev space H~1_0(Ω),where g is the subcritical item to be given.利用空间H10(Ω)的正交分解和极小值原理给出了具临界指数2*的椭圆方程-Δu=λ1u-|u|2*-2u+g(x,u)+h(x)1解的存在性定理,这里次临界项g(x,u)关于u是非线性的,λ1为算子-Δ在H10(Ω)中最小特征值。
