Handouts -- these are supposed to supplement, and not duplicate, what's in the text
Please let me know about any errors in the handouts (more than likely); I may use the notes again for a future course.
|Just the facts: details from the first lecture||DVI|
|Introducing the hyperbolic plane||DVI|
|Gauss-Bonnet and flat structures||DVI|

|Tangent bundles and topological groups||DVI|
|Discreteness and proper discontinuity||DVI|
|Introducing Fuchsian groups||DVI|
|The modular group||DVI|
* By the way, if you're interested in the story of Saccheri, who declared non-Euclidean geometry to be "repugnant to the nature of the straight line," here's a philosophy paper I wrote that makes use of that story to make a point.
