Stability results for some fully nonlinear eigenvalue estimates

open access: yes, 2013
In this paper, we give some stability estimates for the Faber-Krahn inequality relative to the eigenvalues of Hessian operatorsComment: 18 pages, the proofs of Lemma 4.3 and Theorem 4.1 were ...

Double phase problems with variable growth

open access: yes, 2018
We consider a class of double phase variational integrals driven by nonhomogeneous potentials. We study the associated Euler equation and we highlight the existence of two different Rayleigh quotients. One of them is in relationship with the existence of

Monotonicity, continuity and differentiability results for the $L^p$ Hardy constant

open access: yes, 2015
We consider the $L^p$ Hardy inequality involving the distance to the boundary for a domain in the $n$-dimensional Euclidean space. We study the dependence on $p$ of the corresponding best constant and we prove monotonicity, continuity and ...

On an eigenvalue problem associated with the (p, q) − Laplacian

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
Let Ω ⊂ ℝN, N ≥ 2, be a bounded domain with smooth boundary ∂Ω. Consider the following generalized Robin-Steklov eigenvalue problem associated with the operator 𝒜u = − Δpu − Δqu {𝒜u+ρ1(x)|u|p-2u+ρ2(x)|u|q-2u=λα(x)|u|r-2u,   x∈Ω,∂u∂vA+γ1(x)|u|p-2u+γ2(x)|u|

On the second Dirichlet eigenvalue of some nonlinear anisotropic elliptic operators

open access: yes, 2017
Let $\Omega$ be a bounded open set of $\mathbb R^{n}$, $n\ge 2$. In this paper we mainly study some properties of the second Dirichlet eigenvalue $\lambda_{2}(p,\Omega)$ of the anisotropic $p$-Laplacian \[ -\mathcal Q_{p}u:=-\textrm{div} \left(F^{p-1 ...
