摘　　要：借助n-耗散算子及n-次收缩积分半群的相关结论,利用n-次收缩积分半群的Lumer-Phillips定理,研究了n-次收缩积分半群的扰动性,得到了n次收缩积分半群的两个挠动结果.Using related conclusions of n-dissipative operators and n-times contraction integrated semigroups,by means of the Lumer-Phillips theory of n-times contraction integrated semigroups,we discuss the perturbations of n-times contraction integrated semigroups and get two perturbation results on n-times contraction integrated semigroups.

关 键 词：n-耗散算子 n-次收缩积分半群 生成元 扰动
