Payne nodal set conjecture for the fractional $p$ -Laplacian in Steiner symmetric domains

Vladimir Bobkov, Sergey Kolonitskii

Let $u$ be either a second eigenfunction of the fractional $p$ -Laplacian or a least energy nodal solution of the equation $(- Δ)_{p}^{s} u = f (u)$ with superhomogeneous and subcritic…

Entire solutions to the Swift--Hohenberg equation via variational approach

S. B. Kolonitskii, L. M. Lerman, A. I. Nazarov

We study the stationary Swift--Hohenberg equation $(Δ + 1)^{2} u - α u - β u^{2} + u^{3} = 0$ in the whole space $R^{n}$ , $2 \leq n \leq 7$ . We develop and modify the variational approach…

Improved Friedrichs inequality for a subhomogeneous embedding

Vladimir Bobkov, Sergey Kolonitskii

For a smooth bounded domain $Ω$ and $p \geq q \geq 2$ , we establish quantified versions of the classical Friedrichs inequality $∥\nabla u ∥_{p}^{p} - λ_{1} ∥ u ∥_{q}^{p} \geq 0$ , $u \in W_0…

Second-order derivative of domain-dependent functionals along Nehari manifold trajectories

Vladimir Bobkov, Sergey Kolonitskii

Assume that a family of domain-dependent functionals $E_{Ω_{t}}$ possesses a corresponding family of least energy critical points $u_{t}$ which can be found as (possibly nonunique) min…

On a property of the nodal set of least energy sign-changing solutions for quasilinear elliptic equations

Vladimir Bobkov, Sergei Kolonitskii

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 $- Δ_{p} u = f (u)$ in bounded Steiner sym…

On qualitative properties of solutions for elliptic problems with the $p$ -Laplacian through domain perturbations

Vladimir Bobkov, Sergey Kolonitskii

We study the dependence of least nontrivial critical levels of the energy functional corresponding to the zero Dirichlet problem $- Δ_{p} u = f (u)$ in a bounded domain $Ω\subset \math…
