Assignments (listed by due date)

Monday, September 10th:

Read sections 1-5 of the text. Try a few of the exercises. Particular attention should be paid to exercises 1.3, 1.4, 4.3, 5.5-9 in chapter one. These will be discussed in the Wednesday evening session.

Wednesday, September 19th:

Read the remainder of the first chapter of the text. You may skip the material on the Axiom of Choice. (We will return to it later.) The problem session for this week will be Thursday at 6:00 PM, instead of the usual day and time.

Monday, September 24th:

Read the remainder of the first chapter of the text. You may skip the material on the Axiom of Choice.

Wednesday, September 26th:

Start reading chapter two of the text. Complete exercises 1.7.3, 1.8.1, and 1.8.3. These will be collected in class. The problem session this week will be (was) Tuesday September 25th at 6:00 PM instead of the usual day and time.

Monday, October 1st:

Read chapter two, sections 1-3. If you are ambitious, start on chapter 4. Try these exercises on properties of relations from chapter one.

Wednesday, October 3rd:

Continue reading chapter 4. For exercises, prove some of the simple arithmetic properties of cardinal numbers (listed in the various propositions of sections 1-3 of chapter two).

Wednesday, October 10th:

Complete exercises 3, 5, 6, and 7 in chapter two, section 3. These will be collected in class.

Monday, October 22nd:

Supplementary Material


Course Description

This course is an introduction to the fundamentals of set theory. The emphasis will be on the technical material, although there will be some philosophical discussion.

Topics to be covered will include: the standard axioms of set theory; the basic operations on sets (union, intersection, power set etc); the theory of ordinal and cardinal numbers (basic properties, transfinite induction, ordinal and cardinal arithmetic); the axiom of choice and its equivalents; the cumulative hierarchy; and (if there is time) large cardinals and the proofs of independence.


Prerequisites

The course will start from scratch; no background in mathematics or logic is strictly required. However, a background in logic will be helpful; and a certain degree of technical sophistication will be essential.


Course Format

We will more-or-less go through the chapters of the text in order. It is very important for students to do the reading in advance and to do the weekly assignments. Half of these will be handed in for grading. The weekly exercise section is optional, but strongly recommended.


Evaluation

Evaluation will be based upon the mid-term (20%), the final (30%) and the assignments to be set throughout the term (50%). No late assignments will be accepted. For each student, the lowest grade on the assignments will be dropped.
