Description

We discuss the classical and quantum cosmology of a universe filled
with a tachyon condensate and other Born-Infeld type fields. We analyse,
in particular, the cases with a constant potential and with an
inverse square potential. We apply the Wheeler-DeWitt equation of
canonical quantum gravity to these models and show how it can be
appropriately reformulated as a difference equation.
