Disjoint Ces $a ˋ$ ro-hypercyclic operators

Qing Wang, Yonglu Shu

In this paper, we investigate the properties of disjoint Ces $a ˋ$ ro-hypercyclic operators. First, the definition of disjoint Ces $a ˋ$ ro-hypercyclic operators is provide…

The frequent hypercyclicity of unbounded operator

Xiongxun Huang, Yonglu Shu

We establish two Frequent Hypercyclicity Criteria for unbounded operators, inspired by the frameworks of Bayart Grivaux and deLaubenfels Emamirad Grosse Erdmann. These criteria sim…

Dynamic of Time Varying Weighted Backward Shift Operator

Jing Hou, Yonglu Shu

we study the hypercyclic and chaotic properties of the time varying weighted backward shift operator $(T x) (t) = w (t) x (t + a)$ in $L_{p} (0, \infty) (1 \leq p < \infty)$ and $C_{0} [0, \infty)$ . An…

Unbounded Chaotic Weighted Pseudo-shift

Ruxi Liang, Pengyu Qin, Yonglu Shu

In this paper, based on the work of Vijay K. Srivastava and Harish Chandra, we give a characterization of the unbounded hypercyclic weighted pseudo-shift operator $w C_{φ}$ on $\ell^p…
