If you are a student looking for my 1035 course materials they are here, in PDF format mostly. Last year's examples and solutions are here, in a single PDF file .
More recently I put similar materials for this year's MATH2090 course (Real and Complex variables) on an interactive webpage at http://solocavediver.dyn-o-saur.com/sm/.
Back by popular demand.... old admissions quizzes for Trinity College, Cambridge.
Partly written by your humble servant. In TeX DVI format and PDF.
This is mainly a list of those of my papers that are available online. Other
topics will be found at the bottom of the list.

An short, informal CV concerning Dr. Read will be found here in Postscript, and here in TeX
- A list of my other (not-on-the-web) mathematical
papers will be found here in TeX
- Erdos Number: I previously thought that my Erdos number was 5, because
the LRRW paper (see below ) is one of relatively few I have done
in collaboration. Since Volker's Erdos number is 4, I thought mine must
However mine is in fact 4 -many thanks to my research student Matt Daws for
pointing this out; the minimal path is

"Strictly Singular operators and the
Invariant subspace problem". In
or in DVI format. This was published in Studia
Mathematica 132 (3) 203-226 (1999).

Invariant subspace problem";

Paper Amenable and weakly amenable Banach algebras
with compact multiplication , (this paper concerns a
commutative radical Banach algebra with a bounded approximate
identity of normalised powers). This paper is joint work with
Rick Loy, Volker Runde and George Willis, and it appeared in
Jour. Funct. Anal.
171 (2000), 78-114. Available as a DVI file or
in PDF format.
DVI file crab.dvi , containing paper
"Commutative Radical Amenable Banach algebras".
This paper was accepted by
Studia Math., and in the process some corrections were made,
the new version going up on 28/1/00. It has now been published
in Studia Mathematica 140 (3) (2000).
DVI file primes.dvi , containing paper
"All Primes have Closed Range", concerning classification
of elements in commutative Banach algebras, especially
commutative radical Banach algebras.
This paper has now been published in
Bull. Lond. Math. Soc. 33 (2001) 341-346.
A rare opportunity to see Dr. Read
give a proof of a conjecture rather than a counterexample!
Or you can have the
same file in Postscript.
- New paper "Relative amenability and the
B(l^1)." This paper is J. Aust. Math. Soc 80 (2006) 317-333.
"Derivations with large separating subspace" , Proc. Amer. Math. Soc. 130 No. 12 pp 3671-3677 (2002). On a Frechet algebra,
the separating subspace of a derivation from the algebra
to itself may not lie inside the radical. In fact, it may be the
whole space - we give an example.
Updated 15/5/01: Another nice, short paper:
"C* algebras with dense
nilpotent subalgebras" answering a question posed by Dales
that relates both to automatic continuity theory and to
previous work in C* algebras by Herrero and others (e.g. Apostol, Foias
and Voiculescu). Bull. Lond. Math. Soc. 35 (2003) 362-366.

for Read's Recipes - mainly useful to you if you
had dinner cooked by Read and want to know the recipe.
Emphasis is placed on how I actually cooked it,
not how it was supposed to be cooked according to
the original recipes I was half-following.
