On the location of concentration points for singularly perturbed elliptic equations
Simone Secchi, Marco Squassina
By means of a variational identity of Pohožaev-Pucci-Serrin type for solutions of class recently obtained, we give some necessary conditions for locating the concentration po…
Deformation from symmetry for Schrodinger equations of higher order on unbounded domains
Addolorata Salvatore, Marco Squassina
By means of a perturbation method recently introduced by Bolle, we discuss the existence of infinitely many solutions for a class of perturbed symmetric higher order Schrodinger eq…
Unbounded critical points for a class of lower semicontinuous functionals
Benedetta Pellacci, Marco Squassina
In this paper we prove existence and multiplicity results of unbounded critical points for a general class of weakly lower semicontinuous functionals. We will apply a suitable nons…
Spike solutions for a class of singularly perturbed quasilinear elliptic equations
Marco Squassina
By means of a penalization scheme due to del Pino and Felmer, we prove the existence of single-peaked solutions for a class of singularly perturbed quasilinear elliptic equations a…
Multi-peak solutions for a class of degenerate elliptic equations
Alessandro Giacomini, Marco Squassina
By means of a penalization argument due to del Pino and Felmer, we prove the existence of multi-spike solutions for a class of quasilinear elliptic equations under natural growth c…
