Abstract
We find constraints on inflationary dynamics that yield a large local bispectrum and/or trispectrum during two-field slow-roll inflation. This leads to simple relations between the non-Gaussianity parameters, simplifying the Suyama-Yamaguchi inequality and also producing a new result between the trispectrum parameters tNL and gNL.
