Chiral Wgravities for general extended conformal algebras
Abstract
The gauging of any chiral extended conformal symmetry of any twodimensional field theory is achieved by coupling to the appropriate chiral Wgravity. Only a linear coupling to the Wgravity gauge fields is needed. The gauging of algebras with central charges requires the introduction of spinzero gauge fields corresponding to the central charges. The example of Liouville theory is discussed in detail and a new way of coupling it to gravity is obtained.
