摘要: An innite system of stochastic dierential equations for the locations and weights a collection particles is considered. The interact through their weighted empirical measure, V, V shown to be unique solution nonlinear partial equation (SPDE). Conditions are given under which measure has an L2-density with respect Lebesgue measure. c 1999 Elsevier Science B.V. All rights reserved. MSC: 60H15; 60K35; 35R60; 60G09
