报告摘要:In this report, we talk about complex symmetric (weighted) composition operators on some classical Hilbert spaces of analytic functions, and we give an affirmative answer of a conjecture posed by MacDonald and Rosenthal. Concretely, we characterize complex symmetric weighted composition operators with respect to a spectial conjugation, and we investigate cyclicity and hypercyclicity for complex symmetric weighted composition operators. In addition, complex symmetric C_0-semigroups are considered. This is joint work with Prof. Maofa Wang.
