Two positive solutions for a nonlinear parameter-depending algebraic system
2021
The existence of two positive solutions for a nonlinear parameter-depending algebraic system is investigated. The main tools are a finite dimensional version of a two critical point theorem and a recent weak-strong discrete maximum principle.

Normalized Solutions to the Fractional Schrödinger Equation with Potential
2023
AbstractThis paper is concerned with the existence of normalized solutions to a class of Schrödinger equations driven by a fractional operator with a parametric potential term. We obtain minimization of energy functional associated with that equations assuming basic conditions for the potential. Our work offers a partial extension of previous results to the non-local case.

Processi Innovativi e Orientamenti Strategici nelle PMI siciliane. Un'analisi multidimensionale
2010
In 1959, Penrose highlighted how the firm's organisation of economic activity is based on its perception about the adjustment of production to the market, more than on objective evaluation. So, he underlined not just the importance to identify the nature of the determinants of firm behaviour, but also how the assessment of these factors must consider the production context where they originate. Now, this context for Penrose has to be considered as an image in the mind of the entrepreneur of the possibilities and restrictions. In line with this view, and with the recent approach to innovation policies, this work analyses the survey data collected in 2008 on the innovation needs of Sicilian f…

Given a pair of operators a and b acting on a Hilbert space H, such that [a,b]=1, the authors give a method to construct a regular bi-orthogonal pair of sequences in H. They study the relationship between the conditions on a,b,a†,b† and the operators Ae,Be,A†e,B†e, considered by one of the authors in a previous paper, in the set-up of a general theory of bi-orthogonal pair sequences. Then they give a method to construct operators A and B with the so-called D-pseudo bosons conditions, i.e. the commutation rule and some assumptions, on a dense subspace D of H, considered in the literature. Finally, some physical examples are given.
Existence of positive solutions for nonlinear Dirichlet problems with gradient dependence and arbitrary growth
2018
We consider a nonlinear elliptic problem driven by the Dirichlet $p$-Laplacian and a reaction term which depends also on the gradient (convection). No growth condition is imposed on the reaction term $f(z, \cdot,y)$. Using topological tools and the asymptotic analysis of a family of perturbed problems, we prove the existence of a positive smooth solution.
