Supersymmetric quantization of anisotropic scalar-tensor cosmologies

In this paper we show that the spatially homogeneous Bianchi type I and Kan towski-Sachs cosmologies derived from the Brans-Dicke theory of gravity adm it a supersymmetric extension at the quantum level. Global symmetries in th e effective one-dimensional actions characterize both classical and quantum solutions. A wide family of exact wavefunctions satisfying the supersymmet ric constraints are found. A connection with quantum wormholes is briefly d iscussed.
