We will cover the following topics: Completeness of the real number system, basic topological properties, compactness, sequences
and series, absolute convergence of series, rearrangement of series, properties of continuous
functions, the Riemann–Stieltjes integral, sequences and series of functions, uniform convergence,
the Stone–Weierstrass Theorem, equicontinuity, the Arzelà–Ascoli Theorem.

Grading is based on
Almost weekly homework assignments, worth 1/3 of the total grade,
two in-class midterm exams, on dates to be announced, worth 1/3 of the total grade,
a final exam, as scheduled here, worth 1/3 of the total grade.

The final exam will be on December 13th, as scheduled here.

### Additional Resources

Below are some books recommended for further reading.

*Introduction to Analysis* by Arthur Mattuck is a gentler beginning analysis book, with more examples, computations, and motivation, but does not go as far.

*Analysis by Its History*, by E. Hairer and G. Wanner, presents the basic material of this class in historical context, with even better examples, computations, and motivation.

The properties of sets and numbers taken for granted in our course are examined in *The Structure of the Real Number System* by Leon W. Cohen and Gertrude Ehrlich. For those interested in getting to the bottom of things, a good starting point is *The Foundations of Arithmetic* by Gottlob Frege.
