Abstract
Fluctuations of selected observables and their dependence on the size of the system are studied within the framework of an exactly solvable model that mimics the interplay between pairing and long range forces. It is found that thermal mean-field results for fluctuations can yield an adequate estimate of the true fluctuations provided one evaluates those fluctuations in a particular manner.Keywords
