Kleinian Groups and Twistor Theory
, 2013Twistor theory is one of the jewels of mathematics in the 20th Century. A starting point of the celebrated “Penrose twistor programme” is that there is a rich interplay between the conformal geometry on even-dimensional spheres and the holomorphic on their twistor spaces.

Twistor Theory, Self-Duality and Integrability [PDF]
, 1993 This article describes an overview of completely integrable systems based on the self-dual Yang-Mills equations and its twistor correspondence. It also gives a brief survey of results obtained in the area. The Ward construction is briefly described.

TWISTORS AND EINSTEIN-CARTAN THEORY
International Journal of Modern Physics A, 1995After showing that through space-time defects in the presence of torsion we have a way towards the quantization of space-time, we consider the strong analogy between twistors and torsion, both transforming invariantly under the SL (2, C) group, which indicates that twistor theory seems to constitute a mathematical/geometrical basis for the commutation

Perturbative Gauge Theory as a String Theory in Twistor Space
, 2003Perturbative scattering amplitudes in Yang-Mills theory have many unexpected properties, such as holomorphy of the maximally helicity violating amplitudes.

Twistor theory for CR quaternionic manifolds and related structures
, 2009In a general and nonmetrical framework, we introduce the class of CR quaternionic manifolds containing the class of quaternionic manifolds, whilst in dimension three it particularizes to, essentially, give the conformal manifolds.

An Introduction to Twistor Theory: Index
, 1994This book is an introduction to twistor theory and modern geometrical approaches to space-time structure at the graduate or advanced undergraduate level. The choice of material presented has evolved from graduate lectures given in London and Oxford and the authors have aimed to retain the informal tone of those lectures.

Quantisation of Twistor Theory by Cocycle Twist
, 2007We present the main ingredients of twistor theory leading up to and including the Penrose-Ward transform in a coordinate algebra form which we can then ‘quantise’ by means of a functorial cocycle twist.

Internal symmetries in twistor theory
Czechoslovak Journal of Physics, 1982Internal symmetries in the description of massive particles in twistor theory are discussed. A derivation of the form ofn-twistor internal twistor transformations is given. The significance of the local nature of these transformations and the identifications occurring between certain group elements is pointed out.
