Omogeneizzazione di un'equazione differenziale ordinaria avente struttura a scacchiera
Si studia l'omogeneizzazione periodica di una particolare equazione differenziale ordinaria. Si studiano alcune proprietà dell'equazione omogeneizzata e in certi casi se ne trova la formula esplicita.
On 1-regular ordinary differential operators
Solutions to singular linear ordinary differential equations with analytic coefficients are found in the form of Laplace type integrals.

On a certain converse statement of the Filippov-Ważewski relaxation theorem
A certain converse statement of the Filippov-Wažewski theorem is proved. This result extends to the case of time dependent differential inclusions a previous result of Jo’o and Tallos in [5] obtained for autonomous differential inclusions.
