An Introduction to Twistor Theory (London Mathematical Society Student Texts)
"...a quick introduction to some of the deeper problems of twistor theory....book is recommended to anyone seeking to get acquainted with the area."   American Scientist"One of the virtues of this new work is that it is concise and to the point, a property that should particularly commend it to hard-pressed graduate students.  Of necessity this means that a certain amount of preliminary knowledge is assumed of the reader, but this does not extend beyond the contents of introductory courses in general relativity and difficult geometry. Anyone who has these prerequisites and who is interested in twistor theory could hardly do better than to start with this book."   C.J. Isham, Contemporary Physics"...a concise but nevertheless readable introduction to some of the main strands of twistor theory and would certainly be a suitable introduction for a graduate student with a background in general relativity or differential geometry."   J. Vickers, Bulletin of London Mathematical Society
