非负$2\times2$矩阵与非负向量的无穷乘积

Infinite products of nonnegative $2\times2$ matrices by nonnegative vectors

Alain Thomas

摘要:

给定一个非负$2\times 2$矩阵的有限集合$\{M_0,\dots,M_{d-1}\}$和一个非负列向量$V$,我们将每个$(ω_n)\in\{0,\dots,d-1\}^\mathbb N$与列向量序列$\displaystyle{M_{ω_1}\dots M_{ω_n}V\over\Vert M_{ω_1}\dots M_{ω_n}V\Vert}$相关联。给出了该序列对所有\hbox{$(ω_n)\in\{0,\dots,d-1\}^\mathbb N$}收敛的矩阵$M_k$和向量$V$的充要条件,使得$\forall n,\ M_{ω_1}\dots M_{ω_n}V\ne\begin{pmatrix}0\\0\end{pmatrix}$ .

英文摘要:

Given a finite set $\{M_0,\dots,M_{d-1}\}$ of nonnegative $2\times 2$ matrices and a nonnegative column-vector $V$, we associate to each $(ω_n)\in\{0,\dots,d-1\}^\mathbb N$ the sequence of the column-vectors $\displaystyle{M_{ω_1}\dots M_{ω_n}V\over\Vert M_{ω_1}\dots M_{ω_n}V\Vert}$. We give the necessary and sufficient condition on the matrices $M_k$ and the vector $V$ for this sequence to converge for all \hbox{$(ω_n)\in\{0,\dots,d-1\}^\mathbb N$} such that $\forall n,\ M_{ω_1}\dots M_{ω_n}V\ne\begin{pmatrix}0\\0\end{pmatrix}$.
