Abstract


In this paper, we establish the existence of nonoscillatory solutions to neutral dynamic equations with positive and negative coefficients on time scales of the form
\begin{displaymath}
(x(t)-{\int_a^b p(t,\tau{})x(g(t,\tau{}))\Delta{}\tau{}})^\Delta{}+{\sum_{i=1}^l r_{i}(t)x(\delta_{i}(t))}-{\sum_{j=1}^m s_{j}(t)x(\eta_{j}(t))}=0.
\end{displaymath}
Two examples are included to illustrate our presented results. In our approaches, a key role is played by the fixed point technique.
