New Realisations of Minimal Models and the Structure of W-Strings
C. M. Hull
The quantization of a free boson whose momentum satisfies a cubic constraint leads to a $c=\ha$ conformal field theory with a BRST symmetry. The theory also has a symme…
The Geometric Structure of -Gravity
C. M. Hull
The full non-linear structure of the action and transformation rules for $\W_N$-gravity coupled to matter are obtained from a non-linear truncation of those for gravity…
Lectures on W-Gravity, W-Geometry and \W-Strings
C. M. Hull
Lectures given at the Trieste Summer School, 1992. These notes are an update of my review article "Classical and Quantum W-Gravity", preprint QMW-92-1, published in in "Strings and…
Geometry and W-Gravity
C. M. Hull
The higher-spin geometries of -gravity and -gravity are analysed and used to derive the complete non-linear structure of the coupling to matter and its symmetries. T…
