Scientific paper

The pre-big-bad (PBB) scenario is an attempt to use the kinetic energy of the string-theory dilation to drive a period of inflation of the universe. The basic motivations of the PBB scenario are: (1) the existence of exact (spatially homogeneous) dilation-driven inflationary solutions following from the T-duality symmetries of string-theory, and (2) the need to bypass the fact that a tree-level dilation essentially destroys the usual (potential-driven) inflationary mechanism.
