Mathematics for computer science
Notes for computer science students, introducing modular arithmetic, linear algebra and some probability theory, with applications to RSA cryptography, computer graphics, Markov processes and the Google page rank algorithm.
Planar transformations
Planar transformations
An addition to the linear algebra part of the above notes, on affine planar transformations.
A rapid introduction to differential geometry
A rapid introduction to differential geometry
The definition of smooth manifolds, vector bundles and construction of the tangent bundle, critical values, vector and tensor fields (including Sard's theorem and the proof of the Brouwer fixed point theorem), some Riemannian geometry and geodesics, and finally differential forms and de Rham cohomology, ending with a proof of Poincare duality.

Notes on K-theory
Notes on K-theory
In these notes, we give an account of the construction of the K-theory of graded C*-algebras, and its fundamental properties.
Real and complex analysis
Real and complex analysis
Notes on a course I gave for three years at the University of Sheffield. The course covers the basics of normed spaces, differentiation in higher dimensional spaces, the relation between real and complex differentiability, and exactness of differential 1-forms. The fundamental group and covers of spaces are also introduced, and the ideas are applied to complex analysis.
Notes on Galois theory
Notes on Galois theory
A fairly rapid account of Galois theory, complete with exercises, starting from elementary principles. Not much more than the basics of group theory and linear algebra, and the definition of rings and fields are needed.
Non-commutative probability theory
Non-commutative probability theory
Mostly self-contained notes on free probability theory, starting from first principles. Topics covered include the free central limit theorem, random matrices, and the R- and S-transformations.
Measure theory and integration
Measure theory and integration
These notes are a rapid account of measure theory and the Lebesgue integral, starting from first principles.
A primer on some methods in homotopy theory
A primer on some methods in homotopy theory
This article is an exposition of the theory of simplicial sets and spaces, classifying spaces, homotopy colimits, the plus construction and the group completion theorem. The techniques are applied at the end of the article to compare constructions in algebraic K-theory.
A brief review of the theory of symmetric spectra
A brief review of the theory of symmetric spectra
This article is a very short summary of some aspects of the theory of symmetric spectra that I find useful in my work.
Notes on partial differential equations
Notes on partial differential equations
These are notes for a course I gave on partial differential equations in spring 2001 at Odense University. The file is in PostScript format.
