Scientific paper

After introducing a class of string-inspired unconventional cosmologies, I will discuss the spectra of adiabatic scalar and tensor perturbations therein. On the basis of a toy model I will argue that those spectra are quite likely too `blue' to be responsible for the observed large-scale structure of our Universe. I will then discuss a possible way out of this impasse whereby a scale-invariant spectrum of adiabatic density fluctuations emerges through the early decay of the Kalb Ramond axion of string theory.
