主要研究了一类舍临界位势双调和问题.利用Hardy不等式得到一个仅与雏数N有关的上限λ^*且当λ〈λ^*时,不管堆数是一般的还是临界的,该问题都至少有一个正解.
In this paper, we mainly studied a sort of semilinear weighted critical polyharmonic equations, in the critical weighted situation, by using Hardy inequality we can get an upper limit λ^* which is only related to the dimension N, and when λ〈λ^*, the problem has at least one positive solution regardless of whether the dimension is critical or not.
