Supersymmetric structure of the induced W gravities
Jean-Pierre Ader, Franck Biet, Yves Noirot
We derive the supersymmetric structure present in W-gravities which has been already observed in various contexts as Yang-Mills theory, topological field theories, bosonic string a…
A geometrical approach to super W-induced gravities in two dimensions
J. P. Ader, F. Biet, Y. Noirot
A geometrical study of supergravity defined on (1|1) complex superspace is presented. This approach is based on the introduction of generalized superprojective structures extending…
Consistent anomalies of the induced W gravities
M. Abud, J. -P. Ader, L. Cappiello
The BRST anomaly which may be present in the induced gravity quantized on the light-cone is evaluated in the geometrical framework of Zucchini. The cocycles linked by the coh…
Induced Polyakov supergravity on Riemann surfaces of higher genus
J-P Ader, H. Kachkachi
An effective action is obtained for the , induced supergravity on a compact super Riemann surface (without boundary) of genus , as the general solution of th…
The Polyakov action on the supertorus
Jean-Pierre Ader, Hamid Kachkachi
A consistent method for obtaining a well-defined Polyakov action on the supertorus is presented. This method uses the covariantization of derivative operators and enables us to con…
Relating Weyl and diffeomorphism anomalies on super Riemann surfaces
Jean-Pierre Ader, Francois Gieres, Yves Noirot
Starting from the Wess-Zumino action associated to the super Weyl anomaly, we determine the local counterterm which allows to pass from this anomaly to the chirally split superdiff…
