摘要：
We investigate the formation of trapped surfaces in cosmological spacetimes, using constant mean curvature slicing. Quantitative criteria for the formation of trapped surfaces demonstrate that cosmological regions enclosed by trapped surfaces may have matter density exceeding significantly the background matter density of the flat and homogeneous cosmological model. Cosmological trapped surfaces existing at the epoch of recombination would become seeds of the galaxy formation and would be hidden in their centers.
