Simple route to non-Gaussianity in inflation
G. I. Rigopoulos, E. P. S. Shellard, B. J. W. van Tent
We present a simple way to calculate non-Gaussianity in inflation using fully non-linear equations on long wavelengths with stochastic sources to take into account the short-wavele…

Non-linear inflationary perturbations
G. I. Rigopoulos, E. P. S. Shellard
We present a method by which cosmological perturbations can be quantitatively studied in single and multi-field inflationary models beyond linear perturbation theory. A non-linear…
