Twistor theory originated as an approach to unifying quantum theory and general relativity by reformulating basic physics in terms of the geometry of twistor space. Its aspirations remain unfilled, but it has provided some mathematical tools for studying problems in differential geometry, nonlinear equations, and other areas. The volume here is actually the fourth collection of articles reprinted from Twistor Newsletter , a photocopied and partly handwritten journal published occasionally since 1976 by members of Roger Penrose's research group in Oxford. The 89 papers cover the nonlinear graviton and related constructions, spaces of complex null geodesics, hypersurface twistors and Cauchy-Riemann manifolds, and towards a twistor description of general space-time.

Although twistor theory originated as an approach to the unification of quantum theory and general relativity, twistor correspondences and their generalizations have provided powerful mathematical tools for studying problems in differential geometry, nonlinear equations, and representation theory. At the same time, the theory continues to offer promising new insights into the nature of quantum theory and gravitation.
Further Advances in Twistor Theory, Volume III: Curved Twistor Spaces is actually the fourth in a series of books compiling articles from Twistor Newsletter-a somewhat informal journal published periodically by the Oxford research group of Roger Penrose. Motivated both by questions in differential geometry and by the quest to find a twistor correspondence for general Ricci-flat space times, this volume explores deformed twistor spaces and their applications.
Articles from the world's leading researchers in this field-including Roger Penrose-have been written in an informal, easy-to-read style and arranged in four chapters, each supplemented by a detailed introduction. Collectively, they trace the development of the twistor programme over the last 20 years and provide an overview of its recent advances and current status.
