On the asymptotic uniform distribution of sums reduced mod 1. (English) Zbl 0557.60008
Let \(G_ n(x)\) be the distribution function of a sum reduced mod 1 of n independent identically distributed random variables. For the exponential convergence of \(G_ n(x)\) (or its densities \(p_ n(x))\) to the uniform distribution, necessary and sufficient conditions are given. One such condition is \(\sup_{r\neq 0}| f(r)| <1\), where the f(r) are the Fourier coefficients of a summand. If this condition is not satisfied, the rate of convergence can be prescribed arbitrarily. The case of the summands having a lattice distribution is considered in a further paper submitted to the same journal.
