Asymptotic solutions of forced nonlinear second order differential equations and their extensions

open access: yesElectronic Journal of Differential Equations, 2007
Using a modified version of Schauder's fixed point theorem, measures of non-compactness and classical techniques, we provide new general results on the asymptotic behavior and the non-oscillation of second order scalar nonlinear differential equations on

On the asymptotic stability for intermittently damped nonlinear oscillators

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2018
The second order nonlinear differential equation \begin{equation*} x''+h(t,x,x')x'+f(x)=0 \qquad \bigl(x\in\mathbb{R},\ t\in\mathbb{R}_+:=[0,\infty),\ ()':=\tfrac{\text{d}}{\text{d}t}()\bigr), \end{equation*} and a sequence $\{I_n\}_{n=1}^\infty$ of non-

One-dimensional differential Hardy inequality [PDF]

open access: yesJournal of Inequalities and Applications, 2017
We establish necessary and sufficient conditions for the one-dimensional differential Hardy inequality to hold, including the overdetermined case. The solution is given in terms different from those of the known results. Moreover, the least constant for this inequality is estimated.

Differential Inequalities and Carathéodory Functions

open access: yesJournal of Mathematical Analysis and Applications, 1997
Some improvements to several results due to P. T. Mocanu and S. S. Miller [J. Differ. Equations 67, 199-211 (1987; Zbl 0633.34005)] are given. Proofs are based on results of the cited authors and on some ones due to \textit{M. Nunokawa} [Proc. Japan Acad., Ser. A 68, No. 6, 152-153 (1992; Zbl 0773.30020), ibid. 69, No. 7, 234-237 (1993; Zbl 0793.30007)]

Sobolev-Poincaré inequalities for differential forms and currents

open access: yesBruno Pini Mathematical Analysis Seminar, 2019
In this note we collect some results in R^n about (p,q) Poincaré and Sobolev inequalities for differential forms obtained in a joint research with Franchi and Pansu. In particular, we focus to the case p=1.

Weak solutions of functional differential inequalities with first-order partial derivatives

open access: yesJournal of Inequalities and Applications, 2011
The article deals with functional differential inequalities generated by the Cauchy problem for nonlinear first-order partial functional differential equations. The unknown function is the functional variable in equation and inequalities, and the partial
