The Nehari Manifold for p-Laplacian Equation with Dirichlet Boundary Condition

open access: hybridNonlinear Analysis, 2007
The Nehari manifold for the equation −∆pu(x) = λu(x)|u(x)| p−2 + b(x)|u(x)| γ−2u(x) for x ∈ Ω together with Dirichlet boundary condition is investigated in the case where 0 < γ < p.

On the Nehari manifold for a logarithmic fractional Schrödinger equation with possibly vanishing potentials [PDF]

open access: goldMathematica Bohemica, 2022
We study a class of logarithmic fractional Schrödinger equations with possibly vanishing potentials. By using the fibrering maps and the Nehari manifold we obtain the existence of at least one nontrivial solution.

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

open access: greenESAIM: Control, Optimisation and Calculus of Variations, 2019
Assume that a family of domain-dependent functionals EΩt possesses a corresponding family of least energy critical points ut which can be found as (possibly nonunique) minimizers of EΩt over the associated Nehari manifold N(Ωt). We obtain a formula for the second-order derivative of EΩt with respect to t along Nehari manifold trajectories of the form ...

Nehari manifold approach for superlinear double phase problems with variable exponents

open access: greenAnnali di Matematica Pura ed Applicata (1923 -), 2022
AbstractIn this paper we consider quasilinear elliptic equations driven by the variable exponent double phase operator with superlinear right-hand sides. Under very general assumptions on the nonlinearity, we prove a multiplicity result for such problems whereby we show the existence of a positive solution, a negative one and a solution with changing ...

Non-Nehari manifold method for asymptotically periodic Schrödinger equations [PDF]

open access: greenScience China Mathematics, 2014
We consider the semilinear Schr dinger equation $$ \left\{ \begin{array}{ll} -\triangle u+V(x)u=f(x, u), \ \ \ \ x\in {\R}^{N}, u\in H^{1}({\R}^{N}), \end{array} \right. $$ where $f$ is a superlinear, subcritical nonlinearity. We mainly study the case where $V(x)=V_0(x)+V_1(x)$, $V_0\in C(\mathbb{R}^N)$, $V_0(x)$ is 1-periodic in each of $x_1, x_2 ...
