  1. 1. Period integrals and other direct images of D-modules

    University dissertation from Stockholm : Department of Mathematics, Stockholm University

    Author : Ketil Tveiten; Rikard Bøgvad; Uli Walther; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; D-modules; Rings of differential operators; Period integrals; matematik; Mathematics;

    Abstract : This thesis consists of three papers, each touching on a different aspect of the theory of rings of differential operators and D-modules. In particular, an aim is to provide and make explicit good examples of D-module directimages, which are all but absent in the existing literature. READ MORE

  2. 2. Delocalization in nonperiodic systems

    University dissertation from Linköping : Linköpings universitet

    Author : Lars Kroon; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The localization properties of non-interacting linear excitations in one-dimensional aperiodically ordered structures are investigated from a theoretical point of view. The models used have various relevance for real systems, like quasicrystals, photonic crystals, and deterministic aperiodic superlattices. READ MORE

  3. 3. Amoebas and Laurent series

    University dissertation from Stockholm : Matematik

    Author : Mikael Forsberg; [1998]
    Keywords : ;

    Abstract : The amoeba of a polynomialpis the logarithmic image of the zero set of thepolynomial. l/pcan be developed into several Laurent series. Thelogarithmic image of every such Laurent series have a domain ofconvergence and its loga rithmic image is a component of thecomplement of the amoeba of p. This is the background for thethesis subjett. READ MORE
