This course will give the fundamental theory of Teichmullar space, Kleinian groups, and their deformation spaces. The Teichmuller space is a deformation space of a Riemann surface and a Kleinian group is a discontinuous group of linear fractional transformations. The deformation space of a Kleinian group is a generalization of the Teichmuller space. Those theories are important for complex dynamics, topology as well as complex analysis. In this course, those theories will treated consistently by using quasiconformal maps.
This course is a succession of "Advanced Topics in Analysis E" in the previous quarter.
At the end of this course, students are expected to:
-- understand the geometric meanings of the Beltrami equation and quasiconformal mappings.
-- understand Teichmuller space and the Bers embedding.
--understand fundamentals of complex structures of Teichmuller spaces and the deformation spaces of Kleinian groups.
Riemann surfaces, quasiconformal mappings, Teichmuller spaces, Kleinian groups.
