　　英文摘要：Linear dynamics is a young and rapidly evolving branch of functional analysis, which is mainly concerned with the behaviour of iterates of continuous linear operators on separable infinite dimensional topological vector spaces. Such as, hypercyclicity, supercyclicity, chaoticity, transitivity and so on. In this talk, we characterize the disjoint hypercyclic and disjoint supercyclic composition operators on the little weighted Banach space L^0_\mu(T) defined on an unbounded, locally finite metric space T with a distinguished element. We give an explanation of the conditions which are needed and list some examples simultaneously.
