Abstract
In this paper we continue the analysis of the Glauber evolution in Isi ng systems with Kac interactions. In the first paper, we have proved t hat in a continuum limit, called the mesoscopic limit, the magnetizati on density converges to the solution of a non-local deterministic equa tion. Here we study the fluctuations around the limit proving converge nce to a generalized Orsnstein-Uhlenbeck process. We also prove asympt otic formulae for the correlation functions that improve those establi shed in the previous paper and that will be used in a successive paper to study phase separation.
