摘要內容：
The composition in the title refers simply to the composition of two analytic functions. This construction, when carried out in a Hilbert space, can be viewed as a quantization of the group of self-maps of the unit disk. Note that this group is extremely large. For many years people concentrated only on the much smaller sub-group of analytic self-maps, and it has 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.相關檔案：演講1041027.doc
