Abstract
We investigate whether the isotropy problem is naturally solved in inflatio
nary cosmologies inspired by string theory, so called pre-big-bang cosmolog
ies. We find that, in contrast to what happens in the more common 'potentia
l inflation' models, initial anisotropies do not decay during pre-big-bang
inflation.
