Novel Symmetries in Axion-Dilaton Cosmology

Abstract

The symmetry structure of axion-dilaton quantum string cosmology is investigated. The invariance of the string effective action under S-duality group, SU(1,1), facilitates solution of Wheeler-De Witt equation from group theoretic considerations; revealing existence of a new class of wave functions. We discover the an underlying $W$-infinity algebra in this formulation.
