Isoperimetric inequalities for Neumann eigenvalues on bounded domains in rank-1 symmetric spaces
Yifeng Meng, Kui Wang
In this paper, we prove sharp isoperimetric inequalities for lower order eigenvalues of Neumann Laplacian on bounded domains in both compact and noncompact rank-1 symmetric spaces.…
