This book is available at the DU Bookstore.

Course summary

We will cover introductory aspects of measure theory. In particular, we'll discuss what a measure is, what it can be used for, and how one can construct them. We'll define measurability and integrability of functions from this new viewpoint, and discuss how it yields a more general type of integration for functions from the reals to the reals than classical Riemann integration (namely, Lebesgue integration). This will allow us to revisit various topics you've seen from real analysis (such as convergence theorems, pointwise vs. uniform convergence, Fundamental Theorem of Calculus) in a greater and more useful generality. Depending on how much time remains, we may cover some more advanced topics such as L^p spaces, Fourier analysis, or Haar measures on topological groups.

A running theme throughout the course will be comparing measure-theoretic and topological properties. For instance, we'll discuss and prove Littlewood's so-called three principles of real analysis: any (Lebesgue) measurable set is "almost" a union of intervals, any (Lebesgue) measurable function is "almost" a continuous function, and any series of functions which converge pointwise converge "almost" uniformly.

The prerequisites are some course in topology/metric spaces (MATH 3110/4110 or MATH 3260/4110) and real analysis (MATH 3161). If you are not sure whether you are a good candidate for the class, please feel free to come talk to me.

Grading scheme

Your term grade will consist of homework assignments, two midterm exams, and one final exam, broken down in the following way:

30% Homework
30% Midterm Exam
40% Final Exam



You will have one midterm exams on Thursday, February 6th and final exam on Thursday, March 13th. All exams will be in our classroom during classtime (2:00 p.m. - 3:50 p.m.)
