Noncommutative spacetime effect on the slow-roll period of inflation
Hungsoo Kim, Gil Sang Lee, Yun Soo Myung
We study how the noncommutative spacetime affects on inflation. First we obtain the noncommutative power spectrum of the curvature perturbations produced during inflation in the sl…

Second-order corrections to noncommutative spacetime inflation
Hungsoo Kim, Gil Sang Lee, Hyung Won Lee +1
We investigate how the uncertainty of noncommutative spacetime affects on inflation. For this purpose, the noncommutative parameter is taken to be a zeroth order slow-roll pa…
