  1. Only a few have studyed family of problems. we extend the work in [ 26 ] - [ 27 ]. first, under the classical assumption that ( t ) ( t ), we consider the periodic boundary value problem, when / is independent of x ( t ). second, under the case that ( t ) ( t ), we consider the periodic boundary value problem and describe a constructive method which yields two monotone sequences that converge uniformly to extremal solutions to periodic boundary value problems, when / depends on x ( t )

    氣t )這一項的邊值間題更是如此,基於此,我們把微分方程方面的結果推廣到時間模上.首先考慮在下解小於上解的情況下, f不含。 ( t )這一項的周期邊值問題,而後在下解大於上解的情況下,考慮了含有、 ( t )這一項的周期邊值問題,描述了一種構造性方法,構造了兩個單調序列其一致收斂到二階周期邊值問題的極值解
