On p(z)–Laplacian System Involving Critical Nonlinearities

open access: yesJournal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
In this paper, we deal with the existence of at least two nonnegative nontrivial solutions to a p(z)–Laplacian system involving critical nonlinearity in the context of Sobolev spaces with variable exponents on complete manifolds. We have established our main results by exploring both Nehari’s method and doing a refined analysis on the associated fiber ...

On extreme values of Nehari manifold method via nonlinear Rayleigh's quotient [PDF]

open access: greenTopological Methods in Nonlinear Analysis, 2017
We study applicability conditions of the Nehari manifold method for the equation of the form $ D_u T(u)- D_u F(u)=0 $ in a Banach space $W$, where $ $ is a real parameter. Our study is based on the development of the theory Rayleigh's quotient for nonlinear problems.

Nodal solutions for the Choquard equation [PDF]

open access: yes, 2016
We consider the general Choquard equations $$ -\Delta u + u = (I_\alpha \ast |u|^p) |u|^{p - 2} u $$ where $I_\alpha$ is a Riesz potential. We construct minimal action odd solutions for $p \in (\frac{N + \alpha}{N}, \frac{N + \alpha}{N - 2})$ and ...

Local minimizers over the Nehari manifold for a class of concave-convex problems with sign changing nonlinearity

open access: yes, 2017
We study a $p$-Laplacian equation involving a parameter $\lambda$ and a concave-convex nonlinearity containing a weight which can change sign. By using the Nehari manifold and the fibering method, we show the existence of two positive solutions on some ...
