  1. 1. Embedding Theorems for Mixed Norm Spaces and Applications

    Författare :Robert Algervik; Viktor Kolyada; Lars-Erik Persson; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed norms; embeddings; rearrangements; anisotropic fractional Sobolev spaces; anisotropic Besov spaces; mixade normer; inbäddningar; omarrangeringar; anisotropa fractionära Sobolev rum; anisotropa Besov rum; MATHEMATICS; MATEMATIK; Matematik; Mathematics;

    Sammanfattning : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. The work in this direction originates in a paper due to Gagliardo (1958), and was continued by Fournier (1988) and by Kolyada (2005). We consider fully anisotropic mixed norm spaces. LÄS MER

    Sammanfattning : This thesis consists of an introduction and a summary, followed by two papers, both of them on the topic of function spaces on fractals. Paper I: Andreas Brodin, Pointwise Convergence of Haar type Wavelets on Self-Similar Sets, Manuscript. LÄS MER

  5. 4. Embedding Theorems for Mixed Norm Spaces and Applications

    Författare :Robert Algervik; Viktor Kolyada; Javier Soria; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mixed norms; rearrangements; modulus of continuity; embeddings; Sobolev spaces; Besov spaces; Lorentz spaces; Mathematical analysis; Analys; Matematik; Mathematics;

    Sammanfattning : This thesis is devoted to the study of mixed norm spaces that arise in connection with embeddings of Sobolev and Besov type spaces. We study different structural, integrability, and smoothness properties of functions satisfying certain mixed norm conditions. Conditions of this type are determined by the behaviour of linear sections of functions. LÄS MER

  7. 5. Gaussian structures and orthogonal polynomials

    Författare :Lars Larsson-Cohn; Kurt Johansson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Meyer inequality; orthogonal polynomials; Lp-norms; information entropy; finite difference equations; central limit theorem; interpolation theory; Besov spaces; MATEMATIK; MATHEMATICS; MATEMATIK; Mathematics; Matematik;

    Sammanfattning : This thesis consists of four papers on the following topics in analysis and probability: analysis on Wiener space, asymptotic properties of orthogonal polynomials, and convergence rates in the central limit theorem. The first paper gives lower bounds on the constants in the Meyer inequality from the Malliavin calculus. LÄS MER
