Extension of local-type inequality for the higher order correlation functions (1105.5851v2)
Published 30 May 2011 in astro-ph.CO and hep-th
Abstract: For the local-type primordial perturbation, it is known that there is an inequality between the bispectrum and the trispectrum. By using the diagrammatic method, we develop a general formalism to systematically construct the similar inequalities up to any order correlation function. As an application, we explicitly derive all the inequalities up to six and eight-point functions.
