# Measure problem in slow roll inflation and loop quantum cosmology

@article{Corichi2011MeasurePI, title={Measure problem in slow roll inflation and loop quantum cosmology}, author={Alejandro Corichi and Asieh Karami}, journal={Physical Review D}, year={2011}, volume={83}, pages={104006} }

We consider the measure problem in standard slow-roll inflationary models from the perspective of loop quantum cosmology (LQC). Following recent results by Ashtekar and Sloan, we study the probability of having enough e-foldings and focus on its dependence on the quantum gravity scale, including the transition of the theory to the limit where general relativity (GR) is recovered. Contrary to the standard expectation, the probability of having enough inflation, that is close to one in LQC, grows…
