Revisiting non-Gaussianity of multiple-field inflation from the field equation
Shi-Wen Li, Wei Xue
In the present paper, we study the non-Gaussianity of multiple-field inflation model using the method of the field equation. We start from reviewing the background and the perturba…

Generalized Space-time Noncommutative Inflation
Wei Xue, Bin Chen, Yi Wang
We study the noncommutative inflation with a time-dependent noncommutativity between space and time. From the numerical analysis of power law inflation, there are clues that the CM…
