We give subtle, simple and precise results about the convergence or the divergence of the sequence (xn), where xj = f(xj 1) for every integer j ,w hen the initial element x0 is in the neighbourhood of a neutral xed point, i.e. a point x such that f(x )= x withjf 0 (x)j =1( wheref is a C 1 function dened on a subset of R).
