【 摘 要 】

We consider the generalization of two classicalperiodic problems to the context of time scales.On the one hand, we generalize a celebrated result by Castrofor the forced pendulum equation. On the other hand, weextend a well-known result by Nirenberg to a resonantsystem of equations on time scales.Furthermore, the results arenew even forclassical difference equations.
