Course summary

Real analysis is concerned with properties of the set R of real numbers. These include properties of the numbers themselves (limits, sequences, series), the structure of R as a topological space (open and closed sets, compactness, connectedness), and the properties of functions on R (continuity, differentiation, integration).

We will spend most of the term on Chapters 1-4 of Abbott, along with material on uniform convergence (section 6.2) and Riemann integration (7.2, 7.3, 7.6) if time permits. In the first couple of weeks, we will spend significant time on strengthening some fundamentals, in particular proof writing (techniques such as proofs by contradiction and proofs by induction) and familiarity with statements involving quantifiers. Though Chapters 5 and 6 contain very important material, due to time constraints we will need to skip the vast majority of them.

Grading scheme

Your term grade will consist of written weekly homework assignments (which will mostly be taken from the text), short e-mail homework assignments (due every class day), one midterm exam, and one final exam, broken down in the following way.

30% Written homework
5% e-mail homework
30% Midterm exam
35% Final exam


You will have two types of homework for this course. One type will be standard written assignments, to be turned in at the BEGINNING of class on Tuesdays. Assignments turned in after the first 10 minutes of class will be counted as late, and subject to the usual late homework penalty scheme (described below.) These written assignments will be posted here at least one week in advance.

The second type of homework will be very short (shouldn't take longer than 10-15 minutes) e-mail assignments. These will be sent to you one day before every class (except for the first class day, and possibly midterm days.) They can involve material we've covered, or extremely simple material from an upcoming section. They will very rarely (if ever) involve proofs or mathematical arguments, and the solutions will usually consist of only a few sentences; the idea is to help with internalizing definitions and concepts so that class time will be more beneficial for you.

Late assignments will have a percentage subtracted according to the following policy:

3-7 days late: -50%
>7 days late: not accepted


You will have a midterm on May 1st and a final exam on June 5th. Both exams will be in our classroom during classtime. (2:00 p.m. - 3:50 p.m.)
