Schrodinger equation with critical Sobolev exponent [PDF]
In this paper we study the existence of solutions and their concentration phenomena of a singularly perturbed semilinear Schrodinger equation with the presence of the critical Sobolev exponent.

A note on the Neumann problem [PDF]
In this paper we provide an application to the Neumann problem of a recent three critical points theorem.

On the Dirichlet Problem Generated by the Maz'ya--Sobolev Inequality [PDF]
We discuss the attainability of sharp constants for the Maz'ya--Sobolev inequalities in wedges, "perturbed" wedges and bounded domains.

Symmetry of Traveling Wave Solutions to the Allen-Cahn Equation in $\Er^2$ [PDF]
In this paper, we prove even symmetry of monotone traveling wave solutions to the balanced Allen-Cahn equation in the entire plane. Related results for the unbalanced Allen-Cahn equation are also discussed.

Perturbation results for some nonlinear equations involving fractional operators [PDF]
By using a perturbation technique in critical point theory, we prove the existence of solutions for two types of nonlinear equations involving fractional differential operators.

Existence results for nonlinear elliptic problems on fractal domains
Some existence results for a parametric Dirichlet problem defined on the Sierpiński fractal are proved. More precisely, a critical point result for differentiable functionals is exploited in order to prove the existence of a well-determined open interval

(p,2)-equations asymmetric at both zero and infinity
We consider a (p,2){(p,2)}-equation, that is, a nonlinear nonhomogeneous elliptic equation driven by the sum of a p-Laplacian and a Laplacian with p>2{p>2}.

Ground state solutions for nonlinear fractional Schrödinger equations in $\mathbb{R}^N$ [PDF]
We construct solutions to a class of Schr\"{o}dinger equations involving the fractional laplacian. Our approach is variational in nature, and based on minimization on the Nehari manifold.
