Abstract
By using a geometric BRST formalism we investigate the two-dimensional N = 2 and N = 4 superspace geometry. The BRST algebra allows one to generalize the notion of Beltrami variables to the extended supergeometries. Furthermore, this geometric treatment yields a systematic way to derive different off-shell supergravities. Finally we construct the Chern–Simons form and calculate from this the superconformal anomaly for the N = 2 and N = 4 theories.
