报告摘要
In this talk, we give the answers to two open . questions on complex symmetric composition operators. By doing this, we give a complete description of complex symmetric composition operators whose symbols are linear fractional in the unit disk. We also investigate when weighted composition operators acting on Dirichlet spaces are complex symmetric with respect to some special conjugations, and provide some characterizations of Hermitian weighted composition operators on Dirichlet spaces in the unit ball . Furthermore, we give a sufficient and necessary condition for J-symmetric weighted composition operators on Hardy spaces.
