指数有界双连续n阶α次积分C半群的逼近
AApproximation of bi-continuous n-th order α-times integration C-semigroups with exponential boundedness
【摘要】 利用经典算子半群理论中的研究方法,基于双连续n阶α次积分C半群的生成定理,讨论了指数有界双连续n阶α次积分C半群的逼近定理。{T(t)}t≥0,{Tn(t)}t≥0分别是由A、An次生成的指数有界双连续n阶α次积分C半群,在一定条件下,可以得到Ra(λ,An) x→Ra(λ,A) x与Tn(t)x→T (t)x等价。研究结果推广了n阶α次积分C半群相关的逼近定理。
【Abstract】 By using the method of classical operator semigroup theory,based on the generation theorem of bi-continuous n-th order α-times integration C-semigroups with exponential boundedness,we acquired approximation theorem of bi-continuous n-th order α-times integration C-semigroups with exponential boundedness.It is proved if bi-continuous n-th order α-times integration C-semigroups with exponential boundedness{T(t)}t≥0,{Tn(t)}t≥0are generated by A,An respectively,under certain conditions,Ra(λ,An) x→Ra(λ,A) x and Tn (t)x→T (t)x can be obtained.
【Key words】 bi-continuous n-th order α-times integration C-semigroups; approximation; exponential boundedness;
