This collection of notes is slowly, but continually, being added to and polished. I hope that these resources will be useful to the community. Most of these pages are in MathML. The newest of them use HTML5. Firefox has supported MathML for a long time, and other browsers are quickly implementing rendering for it, as it is included in the W3C HTML5 recommendation. It may be necessary to get the STIX fonts, see https://developer.mozilla.org/en/Mozilla_MathML_Project/Fonts. A recent version of Firefox (3 and later) with the STIX fonts should render these notes correctly.

Thank you for your comments on the pure masters program. I have spent many hours processing your comments and making a draft design of a masters program in pure maths. I have tried my best to be faithful to the content and intention of the comments that I received. Having completed the draft, I have a few opinions:

- Point of view: As I progressed through this exercise, it became more and more clear to me that pure mathematics is huge and our goal should be to give a tour of it. In analogy, we must plan 2 days in Sydney, 2 days in Melbourne, 2 days in Adelaide, a day in the SA wine regions, 1 day in Perth, 1 day to the Kalgoorlie gold mines, 1 day in Darwin, 2 days in Kakadu, 1 day at Uluru, 2 days at the Barrier reef diving, 2 days on the Gold Coast, etc. The alternative: to give a semester long course on Kakadu National park, will be fantastically interesting but leave the tourist with a very limited picture of Australia.
- Skills: If we expect our students to be able to use mathematics we will have to teach them about and give them some basic experience with tools that have wide use in pure mathematics research: homological algebra, categories and functors, generators and relations, LOTS of examples--particularly of spaces and actions. We should try to put focus on these things in every course. Of course these tools change with time: homological algebra was probably not one of these fundamental tools in the 1960's, but not including it now would be like expecting our future students to be successful in in life without any knowledge or concept of computers and the internet.
- Marketability: Looking back now at what has come out of my efforts, I think the proposal is pretty attractive to the customer. If I were a beginning masters student,
*I*would be quite attracted by a program that would give me this much overview of the huge world of pure mathematics and the possibility to get some understanding of so many sexy modern words. - Suggested Texts: I tried but failed -- we're going to have to write our own text(s).
- The seminar course: I went back and forth over this because of some strange feeling that it wasn't politically correct and that I would be the recipient of admonition if I included it. Finally I decided that I must face the fact that I think this is as important, and probably more important, than all the other courses combined. Professional mathematicians can't do business without attending and participating in seminars, conferences and workshops and I can't see how I can expect my students to be competitive without analogous experience. It certainly takes plenty of work to run this, keeping track of the students the schedule, the topics and the speakers and tutoring the students as they prepare for their talks. I see no good reason someone couldn't receive a teaching credit for running this.
- Deadline 30 Oct and reality: Comments, suggestions and changes are welcome, but they need to be very constructive and very specific. For example, please do change the 100 word description, not by suggesting it be changed but by drafting a new 100 word decription; please do change the list of courses and topics, not by saying that it should be changed but by writing a new list of courses, 100 word descriptions, list of topics and prerequities.

This course will cover the basics of actions (orbits and modules), universal objects, and homological algebra. There will be a focus on basic definitions and examples. The course will begin with basic linear algebra from the point of view of modules: the Jordan normal form will be presented in the context of a classification of finitely generated modules over C[x] and the classification of finitely generated abelian groups in the context of a classification of Z-modules. Another point of view on these same results is as a classification of orbits in matrix groups. After a review of unversal properties and examples (particularly the exterior algebra), the second part of the course will be an introduction to homological algebra, with a discussion of differential forms, the Koszul and deRahm complexes, and derived functors.

- vector spaces and modules: homomorphisms, free modules, composition series, radicals, semisimplicity
- C[x]-modules: eigenvectors=1dimensional submodules, Jordan canonical form, finitely generated modules over a PID
- Examples of universal objects: quotients, tensor products, symmetric algebras, exterior algebras, polynomial rings, symmetric functions, free associative algebras, localization, completion, free groups and presentations by generators and relations

- Homological algebra: exact sequences, complexes--Koszul and deRahm complexes, cohomology, derived functors--ext and tor,
- Examples of bundles: tangent spaces, differential forms, and cohomology
- Examples of cohomology theories: DeRahm cohomology, singular homology, sheaf cohomology, etale cohomology, group cohomology, Lie algebra cohomology, K-theory, Hochschild cohomology

This course will be a tour of algebraic techniques in modern pure mathematics research. By its nature, the research is motivated by examples, and the first half of this course will have a focus on examples. The first part of the course will focus on the motivation and algebraic construction of the types of spaces used in the study of mirror symmetry, in the Langlands program, and mathematical physics. The second part of the course will be focused on developing the algebraic tools used for the study of these spaces: the derived category, spectral sequences, pushforward and pullback functors.

This course will be an introduction to modern topology. The course will begin with review of "basic topology" including, in particular, the concepts and use of Euler characteristic and Poincare duality. The remainder of the course will have two primary foci: homotopy theory and low dimensional topology. In the homotopy theory part of the course there will be a treatment of basic structures and basic examples: suspensions, loop spaces, classifying spaces, etc, The low dimensional topology part of the course will describe the Thurston classification, discuss surgery methods and study knot complements and the basics of combinatorial group theory and geometric topology.

This course will cover basic tools from analysis. It is loosely divided into subtopics: integration, functional analysis, complex analysis, and harmonic analysis. It will begin with an brief incursion into the world of the logarithm, the Gamma function and Riemann zeta function, using these as the first examples of the ideas of analytic continuation and monodromy. These functions provide motivating examples and tools for many parts of mathematics. The section on harmonic analysis will treat basic Hilbert spaces, proceed to Fourier analysis (the harmonic analysis of R and R/Z), and give an overview of noncommutative harmonic analysis from the point of view of the Laplacian and geometric analysis on symmetric spaces. The section on functional analysis will give an introduction to Banach spaces and the world of bounded operators and convexity. The complex analysis section will study the basics of Riemann surfaces, conformal mapping and harmonic maps. The section on measure theory is the basis of the theory of integration.

Pure mathematics research does not take place in textbooks but in seminars and this is an important part pure mathematics education. Students should attend a variety of seminars, including a research seminar with lectures from outside visitors and a working seminar for students. The research seminar will normally meet once per week, and the student seminar will normally meet once per week. Usually the research seminar will be 1 hour and the student seminar will be 2 hours so that together the usual meeting time for the seminars will total 3 hours per week. Students will be expected to attend both seminars and give a lecture presentation in the working seminar at least once during the semester. Each semester the focus of the student seminar will be chosen based upon current interests of the students and the mentoring faculty.
