Faber Krahn inequality of Robin eigenvalue of the Weighted Laplacian
Daguang Chen, Kui Wang, Anqiang Zhu
In this paper, we study the isoperimetric inequalities for the Robin eigenvalues of the weighted Laplacian with positive Robin parameter in the Euclidean space and the hyper…

Sharp estimates for the Robin Laplacian under a perimeter constraint in hyperbolic space
Daguang Chen, Shan Li
In this paper, we establish a lower bound, in terms of the isoperimetric deficit, for the first eigenvalue of the Robin Laplacian with negative boundary parameter on horosphericall…

On the Bossel-Daners inequality for the p-Laplacian on complete Riemannian manifolds
Daguang Chen, Shan Li, Yilun Wei
In this paper, we obtain the Bossel-Daners inequality for the first eigenvalue of the p-Laplacian with Robin boundary conditions on complete Riemannian manifolds with lower Ricci c…
