Description of my research interests

Most aspects of classical non-Newtonian gravity theory.
Computer algebra applied to differential equations (nothing to do with gravity).

In general relativity and gravity theory, my particular interests are in anisotropic and/or inhomogeneous cosmologies, especially Bianchi cosmologies; exact solutions of the Einstein equations; applications of algebraic computing; theory of gravitational waves; black holes; and asymptotics. I have also written on twistor theory, and thermodynamics.

In computer algebra, I am interested in use of computer algebra systems in teaching and research, in particular the use of REDUCE and SHEEP, in the design and use of manipulators for tensors in differential geometry and gravity theory, and in the solution of ordinary differential equations.


My early work, beginning with my Ph.D., initially under the late Dennis Sciama and subsequently under George Ellis, was in spatially-homogeneous relativistic cosmological models (later to be mentioned in Ellis's FRS citation!). Ellis and I provided the first comprehensive overview of the non-tilted cases, giving a classification, metric forms, various exact solutions, general theorems, and first treatments of the observational and dynamical properties. This led naturally, because those models provided the early examples, to an interest in the early days of quantum cosmology. It also led to an interest in covariant methods and exact solutions in cosmology, areas in which I have continued to work throughout my career.

During a visit by the late Abe Taub to Cambridge, he became interested in my explanation of why the obvious reduced Lagrangian for spatially-homogeneous relativistic cosmologies gave wrong answers in certain cases. He arranged for me to visit Berkeley in 1971 to work on that, and then again the next year for work on the averaged Lagrangian for gravitational waves. The resulting interest in waves has again continued.

Stephen Hawking arranged a series of lectures by Penrose on twistors. My notes on this, originally intended just for private circulation, grew into a well-known review, jointly with Penrose.

After moving to London, through Bill Bonnor I met the late Hans Stephani who soon afterwards asked me to work with him (and Dietrich Kramer and Eddie Herlt) on a book on exact solutions, which came out in 1980. This is now (for all of us) our most widely-cited work. It led to a series of papers on exact solutions in various contexts, a topic on which I still work. A second edition of the book itself, with Cornelius Hoenselaers as fifth author, appeared in 2003, and a corrected paperback edition in 2009.

The 1970s work on the book showed me that some computer algebraic methods were needed. My student Gordon Joly researched possible systems and we made contact with Inge Frick and Jan Åman, authors of SHEEP and CLASSI. Through them I became involved in the equivalence of geometries, following the ideas of Cartan as developed by Anders Karlhede. Stephen Siklos also played a role in development of my ideas here. The theory and practice in this area has led to another still continuing area of work. Later it tied up with work on asymptotics of spacetimes (with, perhaps, links to gravitational wave theory), in particular with Piotr Chrusciel and Jacek Jezierski.

Contact with computer algebra led me to start to use it in teaching and other research, and the teaching use, as well as a role as editor on a book by Stephani on Lie symmetry methods, led me to research in its use for differential equations. This has become a research interest independent of the relativity work.

This sub-page gives access to a complete list of my publications in refer or BibTeX format. The refer format list includes work in preparation ('refer' is a standard Berkeley Unix bibliographic program: the GNU (and hence Linux) version differs slightly. BibTeX is the bibliographic package designed to work with LaTeX)

The same list is also available in HTML form suitable for reading in the browser.
