Query: Novel Symmetries in Axion-Dilaton Cosmology   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.
