About
Welcome to your first Real Analysis course. In this course, we will go back to Calculus 1 and 2 and redo almost everything, but this time with proofs . By the end of the course you will (ideally) not be afraid of ε-δ proofs, uniform continuity, or Riemann sums, but you may be afraid of Cantor sets. We shall see. A slightly more official version of the contents of the course can be found here.
General information
When? MonWedFri 12:00pm-12:50pm.Where? Kirwan 0103.
Who? Aris Papadopoulos (just call me Aris: "R"+"iss" or "air"+"iss").
How? That's a more multifaceted question. Here are some possibilities:
- How to reach me?
{aris}@{umd}.{edu}(without{}, obviously). - How to study? Come to lectures and work through the HWs.
- How to get more help? Come to my office hour (Fridays 11:00am at Kirwan 4311).
Resources
We will be followingBaby Rudinrather closely. The book can be found here. It is not the easiest of reads, so I will also be providing additional notes if we need them. Other good sources include Stephen Abbott's
Understanding Analysis, and (I am told but haven't checked myself) Patrick M. Fitzpatrick's
Advanced Calculus.
