半群生成元的闭性

The closedness of the generator of a semigroup

George Androulakis, Matthew Ziemke

摘要:

本文研究巴拿赫空间上的有界算子半群,使得半群的成员关于各种弱拓扑是连续的,并给出了半群的生成元关于所涉及的拓扑是闭的充分条件.利用半群的拉普拉斯变换证明了这些结果。首先给出了向量值函数关于纯量测度的Pettis可积的充分条件。

英文摘要:

We study semigroups of bounded operators on a Banach space such that the members of the semigroup are continuous with respect to various weak topologies and we give sufficient conditions for the generator of the semigroup to be closed with respect to the topologies involved. The proofs of these results use the Laplace transforms of the semigroup. Thus we first give sufficient conditions for Pettis integrability of vector valued functions with respect to scalar measures.
