Abstract:
This article presents oscillation criteria for n-th order nonlinear
neutral mixed type differential equations of the form
where n is an odd positive integer, a and b are nonnegative
constants,
and
are positive
real constants,
and
and
are ratios of odd positive integers with
.
Some examples are provided to illustrate the main results.
