Let A be a finite alphabet, σ a substitution over A,(u n) n ϵ N a fixed point for σ, and for each a ϵ A, ƒ (a) a real number. We establish, under some assumptions, an asymptotic formula concerning the sum S ƒ (N)= Σ i⩽ N ƒ (u i), N ϵ N. This result generalizes some previous results from Coquet or Brillhart, Erdös, and Morton. Moreover, relations with self-affine functions (in a sense which generalizes a definition from Kamae) are proved. The calculi leave over systems of representation of integers and real numbers.
