摘要: In this paper we examine the derivation of scale-dependent bias due to primordial non-Gaussianity local type in context general relativity. We justify use Poisson equation relativistic perturbation theory and thus as a test non-Gaussianity, using spherical collapse model. The corollary is that form does not receive corrections on scales larger than Hubble radius. This leads formally divergent correlation function for biased tracers mass distribution which discuss.
