Given a probability space (Ω,𝓐, P) and a closed subset X of a Banach lattice, we consider functions f: X × Ω → X and their iterates $fⁿ: X × Ω^{ℕ} → X$ defined by f¹(x,ω) = f(x,ω₁), $f^{n+1}(x,ω) = f(fⁿ(x,ω),ω_{n+1})$, and obtain theorems on the convergence (a.s. and in L¹) of the sequence (fⁿ(x,·)).
