- AbstractWe prove the optimality of a criterion of Koksma (1953) in Khinchin’s conjecture on strong uniform distribution. This verifies a claim of Bourgain (1988) and leads also to a near optimal a.e. convergence condition for series \(∑^{∞}_{k=1} c_k f (kx)\) with \(f ∈ L^2\) . Finally we show that under mild regularity conditions on the Fourier coefficients of \(f\) , the Khinchin conjecture is valid assuming only \(f ∈ L^2\) .
