Abstract: We consider relationship between the rate of convergence to zero of the Faber–Schauder coefficients of continuous functions and the behavior of the greedy algorithm. We construct a continuous function $f$ with Faber–Schauder coefficients $|A_n (f)|=O(\log^{-1} n)$ and divergent greedy algorithm.
Keywords: greedy algorithm, Faber–Schauder system, coefficients of expansion, uniform convergence.
