报告摘要: Let G be a locally compact second countable Hausdorff space with a positive regular Borel measure and $\omega$ is a weight on G. In this article, we provide necessary and sufficient conditions for the hypercyclic weighted translations acting on the weighted space L^{p}(G, omega) in two different cases. Also, some examples are given to illustrate that the results in the first case generalize the characterizations on hypercyclicity for unilateral weighted shifts studied by Salas [TAMS 1995], and the results in the second case generalize Chen and Chu’s work in [PAMS 2011]. Furthermore, we give characterizations of hypercyclicity for adjoint operators of these weighted translations.
