* 강연 제목 : Difference of weighted composition operators

* 초록 : In this talk, we introduce basic concepts about holomorphic function spaces such as Bergman space and Hardy space and composition operators. We also survey progress of composition operators in one or several variables. Finally, we consider the differences of weighted composition operators with (un)bounded and (non)holomorphic weights acting on weigthed Bergman spaces. Thus, we obtain complete characterizations in terms of Carleson measures for bounded/compact differences of such operators. As a consequence, we characterize compact differences of unweighted composition operators on the Hardy spaces in terms of Carleson measures.
