Constructing Hyperbolic Polyhedra using Newton's Method

Abstract: This talk has three parts.  In the first part I will explain the statement of Andreev's classification theorem for compact 3-dimensional hyperbolic polyhedra (whose dihedral angles are non-obtuse).

In the second part I will explain how the proof of Andreev's Theorem provides for an algorithm that, in combination with Newton's Method, can be used to construct hyperbolic polyhedra.  I will then demonstrate the program.

In the third part I will present experimental data such as length spectra and volumes obtained by using SnapPea to study some polyhedral orbifolds constructed using my program.

If there is time remaining I will outline two potentially interesting further experiments.
