Abstract In this note, we prove the Payne-type conjecture about the behaviour of the nodal set of least energy sign-changing solutions for the equation $-\Delta _p u = f(u)$ in bounded Steiner symmetric domains $ \Omega \subset {{\open R}^N} $ under the zero Dirichlet boundary conditions. The nonlinearity f is assumed to be either superlinear or resonant. In the latter case, least energy sign-changing solutions are second eigenfunctions of the zero Dirichlet p-Laplacian in Ω. We show that the… 
Optimal Shapes for the First Dirichlet Eigenvalue of the $p$-Laplacian and Dihedral symmetry
In this paper, we consider the optimization problem for the first Dirichlet eigenvalue λ1(Ω) of the p-Laplacian ∆p, 1 < p <∞, over a family of doubly connected planar domains Ω = B\P , where B is an
Nonradiality of second eigenfunctions of the fractional Laplacian in a ball
Using symmetrization techniques, we show that, for every N ≥ 2, any second eigenfunction of the fractional Laplacian in the N -dimensional unit ball with homogeneous Dirichlet conditions is
Second-order shape derivative along Nehari manifold trajectories
Assume that a family of domain-dependent functionals $E_{\Omega_t}$ possesses a corresponding family of least energy critical points $u_t$ which can be found as (possibly nonunique) minimizers of

In this paper, we prove that the second eigenfunctions of the $p$-Laplacian, $p>1$, are not radial on the unit ball in $\mathbb{R}^N,$ for any $N\ge 2.$ Our proof relies on the variational

In previous work by Castro, Cossio, and Neuberger [2], it was shown that a superlinear Dirichlet problem has at least three nontrivial solutions when the derivative of the nonlinearity at zero is

A Strong Maximum Principle for some quasilinear elliptic equations
In its simplest form the Strong Maximum Principle says that a nonnegative superharmonic continuous function in a domain Ω ⊂ ℝn,n ⩾ 1, is in fact positive everywhere. Here we prove that the same
