摘要 利用变分方法研究了RN上带约束条件的半线性椭圆问题的解,结果表明至少存在一个正解,一个负解以及一个变号解. The paper focuses on the existence of the solutions of a semilinear elliptic eigenvalue problem with constraint in R^N by using variational methods. Among these solutions, we obtained: at least one is positive, one is negative and one is sign changing.
