abstract = {In this paper, we deal with the asymptotic and oscillatory behavior of quasi-linear delay differential equations of fourth order. We first find new properties for a class of positive solutions of the studied equation,              N              a      . As an extension of the approach taken in [1], we establish a new criterion that guarantees that              N              a        =  ∅. Then, we create a new oscillation criterion.}
