Spacetime algebra and electron physics
C. J. L. Doran, A. N. Lasenby, S. F. Gull +2
This paper surveys the application of geometric algebra to the physics of electrons. It first appeared in 1996 and is reproduced here with only minor modifications. Subjects covere…
Analytic solutions to Riemann-squared gravity with background isotropic torsion
A. N. Lasenby, C. J. L. Doran, R. Heineke
Motivated by conventional gauge theories, we consider a theory of gravity in which the Einstein-Hilbert action is replaced by a term that is quadratic in the Riemann tensor. We foc…
Integral equations, Kerr-Schild fields and gravitational sources
Chris Doran, Anthony Lasenby
Kerr-Schild solutions to the vacuum Einstein equations are considered from the viewpoint of integral equations. We show that, for a class of Kerr-Schild fields, the stress-energy t…
Estimating the bispectrum of the Very Small Array data
Sarah Smith, Graca Rocha, Anthony Challinor +30
We estimate the bispectrum of the Very Small Array data from the compact and extended configuration observations released in December 2002, and compare our results to those obtaine…
Conformal Geometry, Euclidean Space and Geometric Algebra
Chris Doran, Anthony Lasenby, Joan Lasenby
Projective geometry provides the preferred framework for most implementations of Euclidean space in graphics applications. Translations and rotations are both linear transformation…
Combined MEM and MHW analysis of CMB observations
R. B. Barreiro, P. Vielva, M. P. Hobson +4
We present a combined maximum-entropy method (MEM) and Mexican Hat wavelet (MHW) analysis in order to recover the different components of the microwave sky. We apply this technique…
