AI中文摘要:
我们研究了 $\mathcal{L}_M(X)$ 中超循环算子的典型动力学性质,其中 $\mathcal{L}_M(X)$ 是 $X$ 上范数至多为 $M$ 的所有有界线性算子的集合,当 $X=\ell_p$,$1<p<\infty$ 时。我们证明,关于 SOT$^*$,典型算子 $T\in \mathcal{L}_M(X)$ 是弱混合的,与给定的超循环算子 $S$ 是弱不相交的,不是拓扑遍历的,并且对于任意 $k\geq 2$,$(T,T^2,\dotsc,T^k)$ 是不相交超循环的。我们还研究了具体族 $\mathcal{M}=\{I+B_w\in \mathcal{L}(X)\colon w\in c_0(\mathbb{Z})\}$ 的典型动力学性质,该族赋予范数拓扑,其中 $B_w$ 是双边加权向后移位。
英文摘要:
We investigate the typical dynamical properties of hypercyclic operators in $\mathcal{L}_M(X)$, the set of all bounded linear operators on $X$ whose norms are at most $M$, when $X=\ell_p$, $1< p<\infty$. We show that, with respect to SOT$^*$, a typical operator $T\in \mathcal{L}_M(X)$ is weakly mixing, is weakly disjoint from a given hypercyclic operator $S$, is not topologically ergodic, and satisfies $(T,T^2,\dotsc,T^k)$ is disjoint hypercyclic for any $k\geq 2$. We also show that the similar typical dynamical properties for the concrete family $\mathcal{M}=\{I+B_w\in \mathcal{L}(X)\colon w\in c_0(\mathbb{Z})\}$, endowed with the norm topology, where $B_w$ is a bilateral weighted backward shift.
