报告摘要：

The composition operators have concentrated only on   analytic 
symbols so far, and it has perhaps been a long sought-after goal to develop a theory with non-analytic 
symbols. A main difficulty is to identify the proper class of self-maps to work with, since 
there exists probably no universal theory to cover all self-maps. In this talk we show that a 
feasible approach is via quasi-conformal mapping, which is by itself a beautiful area in 
analysis, and is not connected with operator theory previously.
