  2. 1. Some Möbius Invariant Spaces of Analytic Functions. Spectrum of the Cesàro Operator

    Author : Anna-Maria Persson; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; subdecomposable; Cesàro operator; atomic decompositions; Hankel operators; duality; integral estimates; Möbius invariant spaces of analytic functions; growth estimates;

    Abstract : This thesis consists of three papers in which different topics in spaces of analytic functions are considered. These papers are: I. "Estimates in Möbius Invariant Spaces of Analytic Functions." II. READ MORE

  4. 2. Spectral estimates and Ambartsumian-type theorems for quantum graphs

    Author : Rune Suhr; Pavel Kurasov; Annemarie Luger; Alexei Rybkin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spectral estimates; quantum graphs; Ambartsumian; trigonometric polynomials; Mathematics; matematik;

    Abstract : This thesis consists of four papers and deals with the spectral theory of quantum graphs. A quantum graph is a metric graph equipped with a self-adjoint Schrödinger operator acting on functions defined on the edges of the graph subject to certain vertex conditions. READ MORE

  5. 3. Estimates for Hardy-type integral operators in weighted Lebesgue spaces

    Author : Larissa Arendarenko; Massimo Lanza de Cristoforis; Luleå tekniska universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : This PhD thesis deals with the theory of Hardy-type inequalities in a new situation, namely when the classical Hardy operator is replaced by a more general operator with a kernel. The kernels we consider belong to the new classes $\mathcal{O}^+_n$ and $\mathcal{O}^-_n$, $n=0,1,... READ MORE

  6. 4. Synthesis, Coding, and Evaluation of 3D Images Based on Integral Imaging

    Author : Roger Olsson; Youzhi Xu; Mårten Sjöström; Tingting Zhang; Aljoscha Smolic; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integral Imaging; 3D images; coding; quality evaluation; H.264 AVC; JP3D; Telecommunication; Telekommunikation;

    Abstract : In recent years camera prototypes based on Integral Imaging (II) have emerged that are capable of capturing three-dimensional (3D) images. When being viewed on a 3D display, these II-pictures convey depth and content that realistically change perspective as the viewer changes the viewing position. READ MORE

  7. 5. Regularity Properties of Oscillatory Integral Operators on Function Spaces

    Author : Anders Israelsson; Wolfgang Staubach; Malabika Pramanik; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : We establish regularity results for a variety of oscillatory integral operators, some of which introduced for the first time in this thesis, in general function spaces such as Besov-Lipschitz and Triebel-Lizorkin spaces. These estimates yield new local and global regularity results for evolutionary partial differential equations... READ MORE
