论文摘要
对于$ C_0 $ -Semigroups $ s $和$ t $的Banach晶格,因此所有时间$ t $ $ s(t)\ le t(t)$,我们证明$ t $的分析性意味着分析性的分析性$ s $。这回答了Arendt在2004年提出的一个开放问题。 我们的证明是基于一个频谱理论论点:我们将正算子的频谱理论应用于乘法函数空间上由$ s $和$ t $引起的乘法运算符。
For positive $C_0$-semigroups $S$ and $T$ on a Banach lattice such that $S(t) \le T(t)$ for all times $t$, we prove that analyticity of $T$ implies analyticity of $S$. This answers an open problem posed by Arendt in 2004. Our proof is based on a spectral theoretic argument: we apply spectral theory of positive operators to multiplication operators that are induced by $S$ and $T$ on a vector-valued function space.
