  1. 16. Maximal theorems and Calderón-Zygmund type decompositions forthe fractional maximal function

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Evgeny Kuznetsov; Luleå tekniska universitet.; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : A very significant role in the estimation of different operators in analysis is played by the Hardy-Littlewood maximal function. There are a lot of papers dedicated to the study of properties of it, its variants, and their applications. READ MORE

  2. 17. Martingale Hardy spaces and summability of the one dimensional Vilenkin-Fourier series

    University dissertation from Luleå tekniska universitet

    Author : George Tephnadze; Luleå tekniska universitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : The classical theory of Fourier series deals with decomposition of afunction into sinusoidal waves. Unlike these continuous waves the Vilenkin(Walsh) functions are rectangular waves. READ MORE
