Research output: Contribution to journalArticlepeer-review


In this paper we study the a.e. strong summability of the quadratical and rectangular partial sums of the two-dimensional Vilenkin–Fourier series for every two-dimensional functions belonging to Llog L . We also study the exponential uniform strong approximation of Marcinkiewicz type of two-dimensional Vilenkin–Fourier series.
