Geometric Topology (MAS 630)

Monday, Wednesday, Friday:14:00-15:00 Room: E6 2411

Instructor: Suhyoung Choi Room: E6-4403

The basic purpose of this course is to study the geometric structures on orbifolds and study
the geometrization of 3-orbifolds following Boileau et al.

in the Fall of 2008. There are many references in here as well. Please download the file.
This will be our lecture note basically for the first seven weeks. Note that I will correct the text
as we go along also.)

 There will be three parts to this course:
Part I: Orbifold theory using mostly my notes. (7 weeks, Feb. 1
nd to March 19th ) I will basically use the material from the Titech course
with small changes. Week 1 note 1 , note 2, note 3-1, note 3-2
Midterm period (no classes)
Part II: ``3-manifolds'' by Hempel and ``Basic 3-Manifold Topology'' by Hatcher. (3 weeks, March 29
th to April 16th )
The lecture notes will be posted later.
Part III: ``3-dimensional Orbifolds and Their Geometric Structures'' by Boileau et al. (4 weeks, April 19
th to May 14th )
Final exam period (no classes)

Note: holidays 2/15, 3/1, 5/5 there will be no classes.

The part III will be presented by the advanced students divided into 11 classes.
Roughly, one student will do one chapter of the book for one hour or so. A long chapter can be divided
into two. Please look at the chapters and divide the book among yourselves. Basically, the book
will be slightly more advanced than my lectures so that you will be able to read it yourselves.
(One should use a presentation software and have a PDF file) If necessary, we can use the Final
exam period also.
