Variational analysis for a nonlinear elliptic problem on the Sierpiński gasket

open access: yes, 2012
Under an appropriate oscillating behaviour either at zero or at infinity of the nonlinear term, the existence of a sequence of weak solutions for an eigenvalue Dirichlet problem on the Sierpinski gasket is proved.

Heteroclinic standing waves in defocussing DNLS equations -- Variational approach via energy minimization [PDF]

open access: yesApplicable Analysis, vol. 89, no. 10, pp. 1591-1602, 2010, 2010
We study heteroclinic standing waves (dark solitons) in discrete nonlinear Schr\"{o}dinger equations with defocussing nonlinearity. Our main result is a quite elementary existence proof for waves with monotone and odd profile, and relies on minimizing an appropriately defined energy functional.

Existence of homoclinic solutions for a class of difference systems involving p-Laplacian

open access: yesAdvances in Differential Equations, 2014
By using the critical point theory, some existence criteria are established which guarantee that the difference p-Laplacian systems of the form Δ(|Δu(n−1)|p−2Δu(n−1))−a(n)|u(n)|q−pu(n)+∇W(n,u(n))=0 have at least one or infinitely many homoclinic ...

Fractional double phase Robin problem involving variable order-exponents and Logarithm-type nonlinearity [PDF]

open access: yes, 2022
In this paper, we study the existence of solutions for the new fractinal Robin equations with variable exponents. Moreover, we deal with the logarithm-type nonlinearity. In particular, we consider two cases: critical and subcritical cases.

Errata: Scattering threshold for the focusing nonlinear Klein-Gordon equation [PDF]

open access: yesAnal. PDE 9 (2016) 503-514, 2015
This article resolves some errors in the paper "Scattering threshold for the focusing nonlinear Klein-Gordon equation", Analysis & PDE 4 (2011) no. 3, 405-460. The errors are in the energy-critical cases in two and higher dimensions.

Existence of homoclinic solutions for a class of second order p-Laplacian systems with impulsive effects

open access: yesBoundary Value Problems, 2014
This paper is concerned with the existence of homoclinic solutions for a class of second order p-Laplacian systems with impulsive effects. A new result is obtained under more relaxed conditions by using the mountain pass theorem, a weak convergence ...

Global minimizers of coexistence for competing species [PDF]

open access: yes, 2010
A class of variational models describing ecological systems of k species competing for the same resources is investigated. The occurrence of coexistence in minimal energy solutions is discussed and positive results are proven for suitably differentiated internal dynamics.

Generalized Burgers equation with rough transport noise [PDF]

open access: yesStochastic Processes and their Applications (2019), available online, 2018
We introduce a new technique for studying well posedness and energy estimates for evolution equations with a rough transport term. The technique is based on finding suitable space-time weight functions for the equations at hand. As an example we study the well posedness of the generalized viscous Burgers equation perturbed by a rough path transport ...

Regularization proximal point algorithm for finding a common fixed point of a finite family of nonexpansive mappings in Banach spaces

open access: yes, 2011
We study the strong convergence of a regularization proximal point algorithm for finding a common fixed point of a finite family of nonexpansive mappings in a uniformly convex and uniformly smooth Banach space.2010 Mathematics Subject Classification ...

Least energy sign-changing solution of fractional $p$-Laplacian problems involving singularities [PDF]

open access: yesDynamics of Partial Differential Equations (2020), Volume 17, Issue 2, pp. 97-115, 2019
In this paper we study the existence of a least energy sign-changing solution to a nonlocal elliptic PDE involving singularity by using the Nehari manifold method, the constraint variational method and Brouwer degree theory.
