Abstract
For a second-order differential equation, we obtain from Opial's inequ ality lower bounds for the spacing between two zeros of a solution or between a zero of a solution and a zero of its derivative. These bound s are expressed in terms of antiderivatives of the potential, and in p articular we derive some new Liapunov type inequalities from them.
