Clifford半群的生成元:多项式预解式及其积分变换

On the generators of Clifford semigroups: polynomial resolvents and their integral transforms

Riccardo Ghiloni, Vincenzo Recupero

摘要:

本文研究Banach双边空间中标量集为任意Clifford代数$\mathit{C}\ell(0,n)$的强连续右线性半群的生成元$\mathsf{A}$.研究了$P(\mathsf{A})$型算子的可逆性,其中$P(x)\in\mathbb{R}[x]$是任意实多项式,并通过由$\mathsf{A}$生成的半群$\mathsf{T}(t)$的Laplace型变换给出了$P(\mathsf{A})^{-1}$的整表示.特别地,我们推导出一个新的整表示的运营商$(\mathsf{A}^2 - 2\mathrm{Re}(q) \,\mathsf{A} + |q|^2)^{-1}$。作为直接结果,我们还获得了$S$的著名整表示的新证明--$\mathsf{A}$的预解算子(也称为$\mathsf{A}$的球形预解算子)。

英文摘要:

This paper deals with generators $\mathsf{A}$ of strongly continuous right linear semigroups in Banach two-sided spaces whose set of scalars is an arbitrary Clifford algebra $\mathit{C}\ell(0,n)$. We study the invertibility of operators of the form $P(\mathsf{A})$, where $P(x)\in\mathbb{R}[x]$ is any real polynomial, and we give an integral representation for $P(\mathsf{A})^{-1}$ by means of a Laplace-type transform of the semigroup $\mathsf{T}(t)$ generated by $\mathsf{A}$. In particular, we deduce a new integral representation for the operator $(\mathsf{A}^2 - 2\mathrm{Re}(q) \,\mathsf{A} + |q|^2)^{-1}$. As an immediate consequence, we also obtain a new proof of the well-known integral representation for the $S$-resolvent operator of $\mathsf{A}$ (also called spherical resolvent operator of $\mathsf{A}$).
