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.)
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).
Feb 7 (together we skimmed 9.2.11, 9.2.12, & 9.2.13 before covering what is in the notes in more detail) Feb 9 Feb 14 Feb 16/18/21 Reading Assignment: Lemma 9.4.6 & Sections 9.4.2, 9.4.3, 9.4.4, 9.4.5, 9.4.6 Feb 23 Feb 28 Mar 2 Mar 16 Mar 21 Mar 23 Mar 28 & conference talk notes Mar 30 Apr 4 Apr 6 Apr 11 Apr 18 Apr 20: class reading & discussion-- Ch 4 up until Section 4.2.4 (will start at this section next time and finish our discussion of the thick-thin decomposition) Apr 25
