Interval oscillation criteria for second order nonlinear forced impulsive differential equations with damping term under variable delay

Abstract

In this paper, interval oscillation of second order forced impulsive differential equations with damping term under variable delay are studied. We follow the Kong and Philos type class functions and pair of functions (H1, H2) to obtain the oscillation criteria. The results obtained in this paper extend some of the existing results. An example is given to illustrate the main result.
