Klappentext This volume is based on lecture courses and seminars given at the LMS Durham Symposium on the geometry of low-dimensional manifolds. This area has been one of intense research during the 1990s! with major breakthroughs that have illuminated the way a number of different subjects interact (for example: topology! differential and algebraic geometry and mathematical physics). The workshop brought together a number of distinguished figures to give lecture courses and seminars in these subjects; the volume that has resulted is the only expository source for much of the material! and will be essential for all research workers in geometry and mathematical physics.
