论文摘要
我们考虑了Courant的Nodal域定理中平等的Laplacian平等的情况，正方形上的Robin边界条件。在前两篇论文中，我们处理了Robin参数$ H> 0 $的情况，分别很小，很小。在本文中，我们调查了$ h <0 \，$的情况。
We consider the cases where there is equality in Courant's nodal domain theorem for the Laplacian with a Robin boundary condition on the square. In our previous two papers, we treated the cases where the Robin parameter $h>0$ is large, small respectively. In this paper we investigate the case where $h<0\,$.
