%0 Journal Article %T Linear delay differential equation with a positive and a negative term %A Faiz Ahmad %J Electronic Journal of Differential Equations %D 2003 %I Texas State University %X We study a linear delay differential equation with a single positive and a single negative term. We find a necessary condition for the oscillation of all solutions. We also find sufficient conditions for oscillation, which improve the known conditions. %K Delay equation %K oscillation %K necessary condition %K sufficient conditions %U http://ejde.math.txstate.edu/Volumes/2003/92/abstr.html
