Critical point localization and multiplicity results in Banach spaces via Nehari manifold technique
Radu Precup, Andrei Stan
In the paper, results on the existence of critical points in annular subsets of a cone are obtained with the additional goal of obtaining multiplicity results. Compared to other ap…

A Nehari manifold method for nonvariational problems
Radu Precup, Andrei Stan
The aim of this paper is to extend the Nehari manifold method from the variational setting to the nonvariational framework of fixed point equations. This is achieved by constructin…

Localization of critical points in annular conical sets via the method of Nehari manifold
Andrei Stan
Using the Nehari manifold method, we establish sufficient conditions such that a smooth functional attains a ground state within an annular domain of a closed cone. The localizatio…
