摘要：

We study the cluster mass function and its evolution in different models with Dark Energy arising from a self-interacting scalar field, with Ratra and Peebles and. SUGRA potentials. Computations are based on a Press and Schechter approximation. The mass functions we obtain are compared with results holding for open models or models with Dark Energy due to a cosmological constant. Evolution results, in some Dark Energy models, closely approach open models. (C) 2002 Elsevier Science B.V. All rights reserved.
