On Liapunov-Type Inequality for Third-Order Differential Equations

Abstract

In this paper, a Liapunov-type inequality has been derived for a class of third-order differential equations of the form,y‴+pty=0,wherepis a real-valued continuous function on [0,∞). The nature of the distance between consecutive two zeros or three zeros has been studied with the help of the inequality. © 1999 Academic Press.
