摘要: : We discuss the progression of growth cosmological structure, from quasilinear evolution nearly Gaussian fluctuations on large scales into highly non-Gaussian, strongly nonlinear structure small scales. A systematic development in perturbation theory describes first departures homogeneity but fails to reproduce fully results. Physical insight, conceptual models, and symmetries are useful strong clustering regime. phenomenological model with input information regime provides enticing results for
