Abstract: By means of the theory on time scales and fixed point theorem,we consider a class of generalized forced higher-order nonlinear neutral dynamic equation on time scales and establish some new sufficient and necessary conditions for the existence of nonoscillatory solutions. The results generalize and improve the known results. An example is given to illustrate the results.
Key words: dynamic equation; time scales; nonoscillatory solution; neutral
