Quantization of two-dimensional cosmology

초록

The generalized kinetic term p(del phi)(2) of a dilaton gives the classical superinflation without recourse to any potential, and the quantum version of the dilaton gravity exhibits the finite curvature. Especially, for p = 2 case, the model corresponds to the RST quantization of the s-wave sector of the four-dimensional Einstein cosmology. Even in the accelerating contraction case of the universe for -4 < p < 0, the curvature singularity does not appear in a certain branch.
