Existence of positive ground solutions for biharmonic equations via Pohožaev-Nehari manifold

open access: yes, 2018
We investigate the following nonlinear biharmonic equations with pure power nonlinearities: \begin{equation*} \begin{cases} \triangle^2u-\triangle u+V(x)u= u^{p-1}u &\text{in } \mathbb{R}^N,\\ u> 0 &\text{for } u\in H^2(\mathbb{R}^N), \end ...

Multiple solutions for a fractional $p$-Kirchhoff system with singular nonlinearity

open access: yesElectronic Journal of Qualitative Theory of Differential Equations
This paper examines a class of fractional p-Kirchhoff systems driven by a nonlocal integro-differential operator with singular nonlinearity. By making use of Nehari manifold techniques, the existence of two nontrivial solutions is established.

Multiple positive solutions for a critical elliptic problem with concave and convex nonlinearities

open access: yesElectronic Journal of Differential Equations, 2014
In this article, we study the multiplicity of positive solutions for a semi-linear elliptic problem involving critical Sobolev exponent and concave-convex nonlinearities. With the help of Nehari manifold and Ljusternik-Schnirelmann category, we prove

Ground state solutions for asymptotically periodic Schrodinger-Poisson systems in R^2

open access: yesElectronic Journal of Differential Equations, 2018
This article concerns the planar Schrodinger-Poisson system $$\displaylines{ -\Delta u+V(x)u+\phi u=f(x,u), \quad x\in \mathbb{R}^2,\cr \Delta \phi= u^2, \quad x\in \mathbb{R}^2, } $$ where V(x) and f(x, u) are periodic or asymptotically periodic in

Effect of Weight Function for a Semilinear Elliptic Equation

open access: yes, 2012
[[abstract]]本論文中,我們觀察半線性橢圓方程中具有變號的加權函數裡,結合了凹凸非線性項的解個數。透過Nehari 流形,我們證明出在這有界的值域下,至少會有兩個解。 In this thesis, we study the combined effect of concave and convex nonlinearities on the number of solutions for a semilinear elliptic equation with sign-changing ...
