Abstract:
In this article we study the oscillation of solutions to
the third order nonlinear functional dynamic equation
on an arbitrary time scale
. Here
with
positive rd-continuous functions on
and
;
the functions
are nonnegative rd-continuous
on
and not all
vanish in a neighborhood
of infinity;
,
.
Our main results extend known results and are illustrated by examples.
