Abstract
Oscillation of solutions of differential equations enjoys wide range of
applications, such as physical sciences, population growth and life
sciences. In this paper, we discuss the oscillation of third-order
nonlinear neutral delay differential equations with unbounded neutral
coefficients and distributed deviating arguments. By using comparison
principles, we relax the restricted conditions and establish new
oscillation theorems, which extend and perfect some related results in
the literature. Finally, our main results are illustrated by two
examples.
