摘要:

考虑时标线性微分方程组的Massera准则, 应用常数变易法证明了时标线性微分方程组yΔ=A(t)y+f(t)存在ω-周期解的充要条件是其存在一个有界解.

Abstract:

We studied Massera type of criteria for linear differential systems on time scales. Using variation of constant formula, we proved the necessary and sufficient condition for the Massera type of criteria for linear differential systems on time scales yΔ=A(t)y+f(t) to possess ωperiodic solutions is the existence of a bounded solution.

Key words: time scales, linear differential systems, variation of constants formula, periodic solution, bounded solution, Massera type of criteria
