Description
We show a global existence theorem for Gowdy symmetric spacetimes
with a positive potential as a model for inflationary cosmology
from string/M-theory.
Also, asymptotic behaviour of the spacetimes is investigated.
Asymptotically velocity terms dominated solutions
near the initial singularity are constructed
and the future asymptotic behaviour of the spacetimes is analysed.
These results are support the validity of the BKL, cosmic no-hair and
strong cosmic censorship conjectures.
