We study solutions of the Wheeler-DeWitt equation corresponding to an S -modular invariant = 1 supergravity model and a closed homogeneous and isotropic Friedmann-Robertson-Walker spacetime. The issues of inflation and the cosmological constant problem are addressed with the help of the relevant wavefunctions. We find that topological-type inflation is consistent from the quantum mechanical point of view and that a solution for the cosmological constant problem along the lines of the strong CP problem arises naturally.
