In this paper, necessary and sufficient conditions are established of the solutions to secondorder halflinear delay differential equations of the form ς y u ′ y a ′ + ∑ j = 1 m p j y u c j ϑ j y = 0 for y ≥ y 0, under the assumption ∫ ∞ ς η − 1 / a d η = ∞. We consider two cases when a c j, where a and c j are the quotient of two positive …Read more
