Classical and quantum cosmology of Born-Infeld type models

Understand

We discuss Born-Infeld type fields (tachyon fields) in classical and quantum cosmology.

• We first partly review and partly extend the discussion of the classical solutions and focus in particular on the occurrence of singularities.
• For quantization, we employ geometrodynamics.
• In the case of constant potential, we discuss both Wheeler-DeWitt quantization and reduced quantization.
