- Abstract
The canonical quantization for N = 1 supergravity in the context of gravitational minisuperspace described by Gowdy T 3 and Bianchi class A cosmological models is analyzed in order to search for physical states. There are indeed physical states in theminisuperspace sector of the theory. This fact entails that the non-physical states conjecture has a restricted validity, and in consequence it cannot be considered a general result.
