Syllabus for Math 103

This syllabus is tentative and will be updated irregularly. The homework page will be updated on the regular basis.

Math 103 will concentrate on Measure Theory and Lebesgue integration with the goal of helping graduate students to prepare for the Analysis certification exam. The exact syllabus will depend on the interests and backgrounds of the students enrolled. From there we will cover as much of Chapters 1-7 as time permits. Ideally the students in the class should have had undergraduate classes in abstract analysis.
