Course Description
This course is an introduction to the wonderful world of measure and integration. You will learn how it is possible to give meaningful answers for the integrals of functions whose Riemann integrals do not exist. Key to this is the idea of a measure, which is a way of giving the size of sets of real numbers which are much more general than the simple intervals used in the Riemann integral. We will rigorously explore questions such as which functions can be integrated in this way, when and where can one differentiate `nice' functions such as monotone functions, when can one interchange the order of integration and when can one measure can be obtained by integrating a density against another measure.
In addition to covering the course material, there will be a very strong emphasis on mathematical rigor and mastering techniques of proof. This is reflected in the rather large percentage of the overall grade which is given over to homework which will be assigned weekly. Please note two things about the homework: firstly, I expect all homework to be submitted using LaTEX and secondly that I will not be taking resubmissions.
In addition to homework, there will be one midterm (provisional date Wednesday October 21) and a final. The material covered in the exams will be partly based on the homework, but there is also some expectation that there will be unseen problems. In addition, you may be asked to give proofs of theorems covered in class and you will be given in advance a list of those theorems which are examinable.
Goals and Objectives
The goals of the course are to have you develop the skills of working with real numbers, limits, continuity and differentiability.
At the conclusion of this semester you should be able to:
