首先我们证明 (*) 对于最小能量节点解成立。然后我们获得一些估计和此类解的渐近轮廓。最后,在某些情况下,我们证明 pup 可以表征为两个格林函数的差,并且对于大 p,节点线与 Ω 的边界相交。
First we prove that (∗) holds for least energy nodal solutions. Then we obtain some estimates and the asymptotic profile of this kind of solutions. Finally, in some cases, we prove that pup can be characterized as the difference of two Green’s functions and the nodal line intersects the boundary of Ω, for large p.
