Existence of Weak Solutions for Nonlinear Time-Fractional p-Laplace Problems
Journal of Applied Mathematics, 2014 The existence of weak solution for p-Laplace problem is studied in the paper. By exploiting the relationship between the Nehari manifold and fibering maps and combining the compact imbedding theorem and the behavior of Palais-Smale sequences in the ...

Multiple positive solutions for a Schr\"odinger-Poisson-Slater system [PDF]
, 2009 In this paper we investigate the existence of positive solutions to the following Schr\"odinger-Poisson-Slater system [c]{ll} - \Delta u+ u + \lambda\phi u=|u|^{p-2}u & \text{in} \Omega -\Delta\phi= u^{2} & \text{in} \Omega u=\phi=0 & \text{on} \partial ...

Blow up results for a viscoelastic Kirchhoff-type equation with logarithmic nonlinearity and strong damping [PDF]
Mathematica Moravica, 2021 A Kirchhoff equation type with memory term competing with a logarithmic source is considered. By using potential well theory, we obtained the global existence of solution for the initial data in a stability set created from Nehari Manifold and prove blow

Multiplicity of positive solutions for a gradient type cooperative/competitive elliptic system
Electronic Journal of Differential Equations, 2020 We study the existence of positive solutions for gradient type cooperative, competitive elliptic systems, which depends on real parameters $\lambda,\mu$. Our analysis is purely variational and depends on finer estimates with respect to the Nehari sets,

Positive solutions for asymptotically linear problems in exterior domains
, 2016 The existence of a positive solution for a class of asymptotically lin- ear problems in exterior domains is established via a linking argument on the Nehari manifold and by means of a barycenter ...

Local minimizers over the Nehari manifold for a class of concave-convex problems with sign changing nonlinearity [PDF]
J. Differential Equations 265 (2018), no. 5, 1894-1921, 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 interval $(0,\lambda^*+\varepsilon)$, where $\lambda^*$ can be characterized variationally.
