Sunto
Gli Autori generalizzano la norma euclidea introducendo la così detta norma D la quale consente di provare tre teoremi i quali collegano il comportamento degli integrali dell'equazione differenziale lineare del secondo ordine $(ry^{\prime})^{\prime} + qy = 0$ col comportamento dell'integrale $$\int_{a}^{t} \Big| \frac{\mu}{r} - \frac{p}{\mu} \Big| (s) \, ds \quad , \quad \mu \in C^{\prime} [a,\infty].$$
