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…
