Abstract
New nonoscillation and oscillation criteria are derived for scalar delay differential equations and and in the critical case including equations with several unbounded delays, without the usual assumption that the parameters , and of the equations are continuous functions. These conditions improve and extend some known oscillation results in the critical case for delay differential equations.
