Abstract: By means of the theory on time scales and inequality technicality,we considered a forced two-dimensional dynamic systems, and established some sufficient conditions for the existence of oscillatory solutions. The results generalized and improved the known results.
Key words: dynamic equation; time scales; oscillation
