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(xiàng)的邊值間題更是如此,基于此,我們把微分方程方面的結(jié)果推廣到時(shí)間模上.首先考慮在下解小于上解的情況下,f不含。(t)這一項(xiàng)的周期邊值問(wèn)題,而后在下解大于上解的情況下,考慮了含有、(t)這一項(xiàng)的周期邊值問(wèn)題,描述了一種構(gòu)造性方法,構(gòu)造了兩個(gè)單調(diào)序列其一致收斂到二階周期邊值問(wèn)題的極值解
