We consider the question: what is the appropriate formulation of Godefroy-Shapiro criterion for tuples of operators? We also introduce a new notion about tuples of operators, S-mixing, which lies between mixing and weakly mixing. We also obtain a suf

We study the dynamical behaviour of weighted backward shifts defined on the little Lipschitzspace of a tree. In particular, we consider hypercyclic, mixed, chaotic and frequent hypercyclic properties ofweighted backward shifts under the homogeneous

Recently, F. Colonna and R. A. Martinez-Avendano raised the open question that whether or not the weighted Dirichlet spaces D α p can support hypercyclic composition operators when p − 2 α p . In this paper, we investigate the hypercyclicity of c

In this paper, we consider the (weighted) backward shift operators on the double sequence spaces. We establish necessary and sufficient conditions for the pair of backward shifts with constant weights as well as variable weights to be hypercyclic, we

In this paper, we give a necessary and sufficient condition for the tensor product of two adjoints of multiplication hypercyclic operators to be mixing and chaotic. These results partially answer a question posed by Felix Martinez-Gimenez and Alfredo

In this paper, the global attractive sets of the simplified Lorenz system are studied according to Lyapunov stability theory. The method for constructing the Lyapunov functions that applied to the former chaotic systems does not work for the simplifi

Currently, chaotic systems and chaos-based applications are commonly used in the engineering fields. One of the main structures used in these applications is chaotic control and synchronization. In this paper, the dynamical behaviors of a new hyperch

This paper has investigated the boundedness of solutions of a complex permanent magnet synchronous motor system. We have obtained the globally exponentially attractive set Ψ λ,m and the ultimate bound Ω λ,m for this system. Furthermore, we can co
