Abstract.
Modest overview of the theory of cone-deformations. We will see its importance in three-dimensional hyperbolic geometry (and therefore in three-dimensional topology): for example in Thurston’s celebrated Hyperbolic Dehn Filling Theorem. The seminar is addressed to non-experts, focusing on geometric intuition and skipping technicalities as much as possible. However, familiarity with hyperbolic geometry and geometric structures (in the sense of Ehresmann-Thurston) would help much.
