| Research Abstract |
I studied the boundary behavior of deformation spaces of Kleinian groups. Especially, I obtained a necessary and sufficient condition in which a sequence of punctured torus groups converges/diverges. Therefore we obtained the whole picture of the self-bumping of the space of punctured torus groups. I also revealed the relation between the Maskit slice and the geometric limit of sequences of liner slices when the associated traces tend to 2. I also studied deformation spaces of 4-dimensional Kleinian groups.
