This is a graduate textbook, aimed at introducing recent graduates with a good grounding in applied mathematics and numerical analysis to various elements related to stochastic differential equations. It should be available in the US from 31st July 2014 and in the UK a little later.

More information can be found at the CUP book web page, the Amazon UK book web page or the Amazon US web page .

An electronic version of the book in secure pdf format is also available from ebooks.com. Note that although other electronic formats are available, the mathematics only displays correctly in pdf format.

MATLAB files associated with the book and solutions (for verified course instructors only) are available HERE .

- S-IFISS: a simple extension of the Incompressible Flow & Iterative Solver Software (IFISS) for stochastic Galerkin finite element discretisations of elliptic PDEs with random diffusion coefficients. This code is also provided as supplementary material for the a posteriori error estimation strategy recently proposed in the paper: Energy norm a posteriori error estimation for parametric operator equations (with Alex Bespalov and David Silvester). SIAM Journal Sci. Comp. 36(2), A339--A363 (2014) .

- PIFISS: Potential Incompressible Flow Software Library

This code illustrates the use of Krylov subspace solvers and preconditioning techniques based on algebraic multigrid for primal and mixed formulations of the steady-state diffusion problem. Test problems are included with discontinuous and anisotropic diffusion coefficients.

- Gaussian random field generators in the NAG Fortran Library

The new routines G05ZMF, G05ZNF, G05ZPF G05ZQF, G05ZRF, G05ZSF and G05ZTF in Mark 24 of the NAG Fortran Library are based on the method of circulant embedding. These were developed during a collaboration between the PhD student Phillip Taylor and NAG (who partially funded the PhD project). The codes can be used to generate realisations of mean zero Gaussian random fields and stochastic processes with both standard and user-defined stationary covariance functions.
