摘要
用变分方法证明H^1(R^N)上一个带限制的半线性椭圆特征问题解的存在性.所获得的三个解:一个是正解,一个是负解.对于第三个解,本文只证明了它的存在性,而没有确定它是正解,负解,还是变号解.
This paper proves the existence of three solutions of a semilinear elliptic eigen- value problem in H1 (RN) with constraint by using variational methods. One is a positive solution; anther one is a negative solution; the third one is not fixed.
