    Författare :Lyazzat Sarybekova; Michael L. Goldman; Luleå tekniska universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fourier multipliers; Lizorkin theorem; Hörmander theorem; regular system; Mathematics; Matematik; Mathematics; Matematik;

    Sammanfattning : This PhD Thesis is devoted to the study of Fourier series and Fourier transform multipliers and it contains four papers (papers A - D) together with an introduction, which put these papers into a general frame. This extensive introduction can also be seen as an independent description of this important area including the historical development and the most important results. LÄS MER

    Sammanfattning : This Licentiate Thesis is devoted to the study of Fourier series and Fourier transform multipliers and contains three papers (papers A - C) together with an introduction, which put these papers into a general frame. In paper A a generalization of the Lizorkin theorem on Fourier multipliers is proved. LÄS MER
