Let (X,T) be a dynamical system. The recurrence of a point x I-elated
to a function Phi : X --> R-d is described by the limit of ergodic mea
ns n(-1) Sigma(j=0)(n-1) Phi(T(j)x). We are interested in estimating t
he size of the set of points with a prescribed recurrence. The dimensi
ons of such sets are computed in the case of symbolic spaces. (C) Acad
