Basic Theorems on Diferential Equations In this theorem, the derivatives of the solution at the end points of the interval (2.3) should be understood to be the suitable one-sided derivatives. This convention will be used hereafter without further mention. In the Lipschitz condition (2.2), the constant L is called the Lipschitz constant.
