Abstract:

The article is concerned with oscillation of nonautonomous neutral dynamic delay equations on time scales. Sufficient conditions are established for the existence of bounded positive solutions and for oscillation of all solutions of this equation. Some results extend known results for difference equations when the time scale is the set bZ+ of positive integers and for differential equations when the time scale is the set R of real numbers.

Key words: Time scale, Delta-derivative, neutral delay equation, oscillation
