The Differentiability of C0-Semigroups with Respect to a Parameter with an Application
【摘要】 考虑了 C0 -半群关于参数的可微性 ,而参数含在半群的无穷小生成元中 .证明了 :无穷小生成元关于参数的广义连续性及强可微性蕴含着该 C0 -半群关于参数的可微性 .这些结果被应用于证明线性延滞微分方程的解关于延滞量的可微性质
【Abstract】 This paper considers the differentiability of C0 -semigroups with respect to ( w.r.t.) parameters contained in their infinitesimal generators. It is proved that the generalized continuity and strong differentiability of their infinitesimal generators w.r.t.parameters imply the differentiability of the C0 - semigroups.The results are applied to the differentiability of the solution of a lineardelay differential equation w.r.t.its delays.
