Some footprints of Marcinkiewicz in summability theory

Ferenc Weisz (2011)

Banach Center Publications

Similarity:

Four basic results of Marcinkiewicz are presented in summability theory. We show that setting out from these theorems many mathematicians have reached several nice results for trigonometric, Walsh- and Ciesielski-Fourier series.
