We investigate the canonical quantization of supergravity N=1 in the case ofa midisuperspace described by Gowdy $T^3$ cosmological models. The quantumconstraints are analyzed and the wave function of the universe is derivedexplicitly. Unlike the minisuperspace case, we show the existence of physicalstates in midisuperspace models. The analysis of the wave function of theuniverse leads to the conclusion that the classical curvature singularitypresent in the evolution of Gowdy models is removed at the quantum level due tothe presence of the Rarita-Schwinger field.Comment: 25 pages and 2 figure
