Critical points of second Neumann eigenfunctions on some convex domains in two-dimensional space forms
Haiyun Deng, Xuyong Jiang, Xiaoping Yang
In this paper, we investigate critical points of second Neumann eigenfunctions on convex domains in the two-dimensional space forms. We approach this problem from three complementa…

Critical points of the second Neumann eigenfunctions on the quadrangles with symmetry
Haiyun Deng, Changfeng Gui, Xuyong Jiang +3
In this paper, we focus primarily on the symmetry properties of the second Neumann eigenfunction with respect to the symmetry axis or symmetry center of the relevant domain …
