摘要：

We propose an analytic description of the direct mergings that involve galaxies in groups. We predict shape and evolution of the distribution of the galaxian masses in these finite systems, including the formation of a cD-like merger that analytically appears as a critical phenomenon. Our findings constitute a close counterpart of many N-body results. Similar aggregation phenomena conceivably take place in other cosmic structures.
