[ Abstract ]
In this talk, I explain a complex analytic method and its applications
for the study of quasisymmetric homeomorphisms of the circle by extending them to the unit disk quasiconformally.
In RIMS conference "Open Problems in Complex Geometry'' held in 2010,
I gave a talk entitled "Problems on infinite dimensional Teichmueller spaces", and
mentioned several problems on the fixed points of group actions on
the universal Teichmueller space and its subspaces, and the rigidity of conjugation of
certain groups of circle homeomorphisms.
I will report on the development of these problems since then.
