Comparison results for a nonlocal singular elliptic problem
Barbara Brandolini, Ida de Bonis, Vincenzo Ferone +1
We provide symmetrization results in the form of mass concentration comparisons for fractional singular elliptic equations in bounded domains, coupled with homogeneous external Dir…
A sharp estimate for Neumann eigenvalues of the Laplace-Beltrami operator for domains in a hemisphere
Rafael D. Benguria, Barbara Brandolini, Francesco Chiacchio
Here we prove an isoperimetric inequality for the harmonic mean of the first non-trivial Neumann eigenvalues of the Laplace-Beltrami operator for domains contained in a hemis…
Optimal lower bounds for eigenvalues of linear and nonlinear Neumann problems
B. Brandolini, F. Chiacchio, C. Trombetti
In this paper we prove a sharp lower bound for the first nontrivial Neumann eigenvalue for the -Laplace operator in a Lipschitz, bounded domain in . Our estim…
A sharp lower bound for some Neumann eigenvalues of the Hermite operator
B. Brandolini, F. Chiacchio, C. Trombetti
This paper deals with the Neumann eigenvalue problem for the Hermite operator defined in a convex, possibly unbounded, planar domain , having one axis of symmetry passing throug…
