Abstract: By means of the theory on time scales and Banach contraction principle, the auchor considers the existence of positive solutions of generalized forced higher-order neutral dynamic equation on time scales and establishs some new sufficient conditions for the existence of positive solutions. An example is given to illustrate the results.
Key words: dynamic equation; time scales; positive solution; neutral
