A unified treatment using critical point methods of the existence of multiple solutions for superlinear and sublinear neumann problems

, 2011
In this paper we present a framework which permits the unified treatment of the existence of multiple solutions for superlinear and sublinear Neumann problems. Using critical point theory, truncation techniques, the method of upper-lower solutions, Morse

Multiple positive solutions for Schrödinger-Poisson system with singularity on the Heisenberg group

Journal of Inequalities and Applications
In this work, we study the following Schrödinger-Poisson system { − Δ H u + μ ϕ u = λ u − γ , in  Ω , − Δ H ϕ = u 2 , in  Ω , u > 0 , in  Ω , u = ϕ = 0 , on  ∂ Ω , $$ \textstyle\begin{cases} -\Delta _{H}u+\mu \phi u=\lambda u^{-\gamma}, &\text{in ...

Infinitely many positive solutions for fractional differential inclusions

Electronic Journal of Differential Equations, 2016
In this article, we study a class of fractional differential inclusions problem. By nonsmooth variational methods and the theory of the fractional derivative spaces, we establish the existence of infinitely many positive solutions of the problem under

Nonsmooth Schur-Newton methods for nonsmooth saddle point problems. [PDF]

, 2013
We introduce and analyze nonsmooth Schur-Newton methods for a class of nonsmooth saddle point problems. The method is able to solve problems where the primal energy decomposes into a convex smooth part and a convex separable but nonsmooth part.

PRIN 2009: Critical point theory and perturbative methods for nonlinear differential equations. Hamiltonian Systems and Partial Differential Equations

, 2011
Many partial differential equations arising in Physics can be seen as innite dimensional Hamiltonian systems. Main examples are the nonlinear Schrodinger (NLS) and wave (NLW) equations, the beam, membrane and Kirkhoff equations in elasticity theory, the ...
