Quasi-conformal surgery for

the construction of Herman rings


Mr. Mingxi Wang

Department of Mathematics
The University of Hong Kong





About twenty years ago, by introducing the method of quasi-conformal surgery, Shishikura showed how one can construct rational functions with Herman rings. His main idea is to cut and paste two Siegel disks to produce one Herman ring. In this talk, we shall explain his construction carefully.
