Abstract: Two-dimensional analogs of famous Zygmund and Szasz tests for absolute convergence of Fourier–Vilenkin series are established. Also it is proved that two-dimensional Szasz test is the best possible in the certain sense.
Key words: absolute convergence, Fourier–Vilenkin series, modulus of continuity, functions of bounded $p$-fluctuation.
