## Abstract Sufficient conditions are established for oscillation of second order super half linear equations containing both delay and advanced arguments of the form equation image where __ฯ~ฮด~__ (__u__) = |__u__ |^__ฮด__ โ1^__u__; __ฮฑ__ > 0, __ฮฒ__ โฅ __ฮฑ__, and __ฮณ__ โฅ __ฮฑ__ are real numbers; __k
In this note, a Massera type criterion for the existence of periodic solutions for linear functional differential equations with advance and delay is established. Because of the presence of an advanced argument, the definition of the fundamental solution operator seems unknown. Hence a method differ
