  In loop quantum gravity, modifications to the geometrical density cause a
self-interacting scalar field to accelerate away from a minimum of its
potential. In principle, this mechanism can generate the conditions that
subsequently lead to slow-roll inflation. The consequences for this mechanism
of various quantization ambiguities arising within loop quantum cosmology are
considered. For the case of a quadratic potential, it is found that some
quantization procedures are more likely to generate a phase of slow--roll
inflation. In general, however, loop quantum cosmology is robust to ambiguities
in the quantization and extends the range of initial conditions for inflation.
