单值算子〔m仪.山咖yo伴rator;MO“0皿poM”加onepa-TOP」 有界线性算子U(T),它将Banach空间中微分方程交=A(t)x(其中A(t)是依赖于t的有界算子,即连续的、且以T为周期的)的解的初值x(0)=x。与在时刻T的值相联系:x(T)=U(T)x。对于每一个解,x(t十T)=U(T)x(t).在有限维空间中,u(T)对应于单值矩阵(monod比myIT坦tr认).单值算子的谱的位置影响着方程周期解的存在时,无穷远处解的性态,此方程化为常系数方程的可约性,以及指数分叉的存在性,对于A(O和f(灼具有周期性的非齐次方程交=A(t)x十f(t),其周期解的存在和唯一性问题也借助于单值算子谱来解决 亦见B田.山空间中微分方程的定性理论(QI坦11-扭七ve theo习ofd正rerential闪Uations inBanachsPaces).
