A Proof of the Bihali Lemma |

Abstract: | According to the Bihali lemma, we can get larger existential interval of the solutions of differential equations. It is evident that the Bihali lemma is very important. However, the proof for this lemma cannot be founded up to now. This paper proves this lemma and presents examples illustrating its importance. |
