    Abstract : .... READ MORE

  4. 2. Retrieval of equivalent currents by the use of an integral representation and the extinction theorem --- radome applications

    Author : Kristin Persson; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; extinction theorem; inverse source problem; integral representation; radome diagnosis; near-field transformation;

    Abstract : The aim of this thesis is to solve an inverse source problem. The approach is based on an integral representation together with the extinction theorem. Both a scalar and a full-wave integral representation are implemented and solved by a Method of Moment procedure. READ MORE

  5. 3. Integral representations of Herglotz-Nevanlinna functions

    Author : Mitja Nedic; Annemarie Luger; Alexandru Aleman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; integral representations; Herglotz-Nevanlinna functions; several complex variables; Mathematics; matematik;

    Abstract : In this thesis, we study integral representations of Herglotz-Nevanlinna functions, that is to say holomorphic functions defined on a product of several copies of the complex upper half-plane having non-negative imaginary part. The manuscript is divided into three parts, beginning with a general introduction followed by two papers. READ MORE

  6. 4. The one-dimensional Kondo Lattice in the Majorana Fermion representation

    Author : Matteo Bazzanella; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Majorana fermions; kondo lattice; path integral; spin-selective kondo insulator;

    Abstract : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. READ MORE

  7. 5. Toric varieties and residues

    Author : Alexey Shchuplev; Mikael Passare; Alekos Vidras; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; toric variety; residue; residue current; integral representation; MATHEMATICS; MATEMATIK; matematik; Mathematics;

    Abstract : The multidimensional residue theory as well as the theory of integral representations for holomorphic functions is a very powerful tool in complex analysis. The computation of integrals, solving algebraic or differential equations is usually reduced to some residue integral. READ MORE
