Contribution

It provides a detailed analysis of boundary conditions in loop quantum cosmology and their relation to inflation, highlighting differences from traditional approaches.

Findings

Loop quantum cosmology offers alternative initial conditions for the universe.

Boundary conditions influence the onset of inflation in quantum cosmology.

Comparison shows differences between loop quantum cosmology and Wheeler-DeWitt results.

Abstract

Loop quantum cosmology of the closed isotropic model is studied with a special emphasis on a comparison with traditional results obtained in the Wheeler-DeWitt approach. This includes the relation of the dynamical initial conditions with boundary conditions such as the no-boundary or the tunneling proposal and a discussion of inflation from quantum cosmology.
