Although this study guide is focused on Oxford, much of its advice is relevant (indeed,
crucial) to anyone learning mathematics.

A Guide to Writing in Mathematics Classes
 If you ever find yourself preparing an abstract or a summary of your own research,
you should read How to
get your abstract rejected. Heck, read it anyway, it's quite funny and you've probably
seen all of the sins it outlines committed in the course texts you've had to read.
My research interests are in operator algebra and operator theory.
In particular, most of my papers are about limit algebras, infinitedimensional
operator algebras that are limits of finitedimensional algebras.
In spite of being "almost finitedimensional", they have some quite suprising
properties.
I've put more information, including abstracts of my papers, on a separate
page.
Together with Kenneth R. Davidson
of the University of Waterloo, I have written an introductory analysis textbook,
called Real Analysis and Applications.
The publisher, SpringerVerlag New York, has a
webpage for the book.
(This is an updated version of Real Analysis with Real Applications,
published by PrenticeHall in 2001.)
I've posted
the table of contents and the preface for the book.
There is also a table of errata.
Feel free to email us with comments on the book.
On a related note, I have a short
list of articles and books
that I've found useful in teaching analysis.
These are typesetting programs that are defacto standards for
mathematics and physics papers.
The hardest part of getting started with them is finding
good model documents to modify.
In the absence of better models, I offer a few documents of
my own, listed
here.
There are a multitude of good sites on TeX.
I would particularly recommend the
Comprehensive TeX Archive Network
and the American Mathematical Society's page on
TeX Resources.
There are two books I would particularly recommend:
 LaTeX: A Document Preparation System by Leslie Lamport,
Second Edition, AddisonWesley, ISBN: 0201529831.
 A Guide to LaTeX 2e by Helmut Kopka and Patrick W. Daly,
Second Edition, AddisonWesley, ISBN: 020142777X.
The first is the original user's manual by the author of LaTeX.
But what matters most to me, personally, is being able to communicate
to others my sense of what mathematical research is all aboutthe
quest for truth and the inner joy that comes from surrendering oneself
to it.
