具有有界$H{^\infty}$ -演算的$L_p$上半群的结构

On the structure of semigroups on $L_p$ with a bounded $H{^\infty}$-calculus

Stephan Fackler

摘要:

证明了$L_p$ -空间上的有界解析半群对某些$φ< \fracπ{2}$有界$H^{\infty}(Σ_φ)$ -演算当且仅当该半群可由某些较大的在实直线上为正压缩的$L_p$ -空间上的有界解析半群在限制到不变子空间后,通过不变子空间和相似变换进行因子分解而得到.

英文摘要:

We show that a bounded analytic semigroup on an $L_p$-space has a bounded $H^{\infty}(Σ_φ)$-calculus for some $φ< \fracπ{2}$ if and only if the semigroup can be obtained, after restricting to invariant subspaces, factorizing through invariant subspaces and similarity transforms, from a bounded analytic semigroup on some bigger $L_p$-space which is positive and contractive on the real line.
