Uniqueness Theorems for Ordinary Differential Equations with Hölder Continuity

Yifei Pan, Mei Wang, Yu Yan

We study ordinary differential equations of the type $u^{(n)} (t) = f (u (t))$ with initial conditions $u (0) = u^{'} (0) = ... = u^{(m - 1)} (0) = 0$ and $u^{(m)} (0) \neq = 0$ where $m \geq n$ ,…

A Hopf's Lemma for Higher Order Differential Inequalities and Its Applications

Yifei Pan, Mei Wang, Yu Yan

We establish a sequential Hopf's Lemma for higher order differential inequalities in one variable and give some applications of this result.
