Abstract: In cosmology, various kinds of random fields play important roles, including 3D distributions of galaxies and other astronomical objects, 2D distributions of cosmic microwave background radiations and weak lensing fields, etc. The features of non-Gaussianity in these fields contain a lot of cosmological information. In this talk, I will present a method to analytically describe the effects of weak non-Gaussianity field statistics, such as the peak abundance, peak correlations, Minkowsky functionals, etc.
