The author studies the sums $$s^ f(n)=\sum_{i\leq n}f(u_ i)$$ where $$(u_ i)$$ is a fixed point of a substitution (see the previous review Zbl 0718.11008). In this paper he concentrates on the behavior of $$\sum_{n<N}s^ f(n)$$. In particular, he proves that the centered moments of the distribution of $$s^ f(n)$$ have the same property as the centered moment of a centered Gaussian distribution (assuming that the second eigenvalue of the matrix of the (primitive) substitution is equal to 1, and some additional reasonable conditions). - The results of the author answer a conjecture of C. Godrèche, J.-M. Luck and F. Vallet [Quasiperiodicity and types of order: a study in one dimension, J. Phys. A 20, 4483–4499 (1987)] and a conjecture of J.-M. Luck.
