Critical nonlocal systems with concave-convex powers

open access: yes, 2016
By using the fibering method jointly with Nehari manifold techniques, we obtain the existence of multiple solutions to a fractional $p$-Laplacian system involving critical concave-convex nonlinearities provided that a suitable smallness condition on the ...

Existence Results for a Class of the Quasilinear Elliptic Equations with the Logarithmic Nonlinearity

open access: yesJournal of Function Spaces, 2020
In this paper, the nonlinear quasilinear elliptic problem with the logarithmic nonlinearity −div∇up−2∇u=axφpulogu+hxψpu in Ω⊂Rn was studied. By means of a double perturbation argument and Nehari manifold, the authors obtain the existence results.

Variational properties and orbital stability of standing waves for NLS equation on a star graph

open access: yes, 2014
We study standing waves for a nonlinear Schr\"odinger equation on a star graph {$\mathcal{G}$} i.e. $N$ half-lines joined at a vertex. At the vertex an interaction occurs described by a boundary condition of delta type with strength $\alpha\leqslant 0 ...

Comparison moduli spaces of Riemann surfaces

open access: yes, 2017
We define a kind of moduli space of nested surfaces and mappings, which we call a comparison moduli space. We review examples of such spaces in geometric function theory and modern Teichmueller theory, and illustrate how a wide range of phenomena in ...
