Course Description
In this course we will survey various aspects of 3-manifolds including: 2-dimensional orbifolds, Seifert fibered spaces, Thurston's 8 geometries, separability properties, Haken manifolds, and other items as time permits (Virtually Fibered Theorem, Virtual Haken Theorem, decompositions of 3-manifolds, etc.)

Jan 19 (I only got through the proof of Prop 9.2.14)
Reading Assignment for week of Jan 23: this only works if you actually do the reading!! feel free to work together
Martelli's book Sections 9.2.6, 9.2.7 (you will need to read Sec 1.7.5 for this and you can skip exercise 9.2.22), 9.2.8 and 9.2.9 (you can skim the proofs in these two sections, but you need the statements of results for the next section), and finally Section 9.2.10 (this is the really important proof that I want you to go through carefully).
