Classical and Quantum W -gravity

  title={Classical and Quantum W -gravity},
  author={Chris M. Hull}
Classical W-gravities and the corresponding quantum theories are reviewed. W-gravities are higher-spin gauge theories in two dimensions whose gauge algebras are W-algebras. The geometrical structure of classical W-gravity is investigated, leading to surprising connections with self-dual geometry. The anomalies that arise in quantum W-gravity are discussed… CONTINUE READING
