  4. 3. On direct and inverse scattering problems in dimension one

    Författare :Pavel B. Kurasov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Direct and inverse scattering problems for the Schrödinger operator in dimension one are investigated. Relations between the scattering problems defined by regular and zero range potentials are investigated.Correct mathematical definition of the «^'-interaction is introduced and investigated in detail.

  5. 4. Generalized Titchmarsh-Weyl functions and super singular perturbations

    Författare :Christoph Neuner; Annemarie Luger; Pavel Kurasov; B. Malcolm Brown; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Generalized Titchmarsh-Weyl function; Super singular perturbations; Strongly singular potentials;

    Sammanfattning : In this thesis we study certain singular Sturm-Liouville differential expressions from an operator theoretic point of view.In particular we are interested in expressions that involve strongly singular potentials as introduced by Gesztesy and Zinchenko. LÄS MER

  7. 5. Higher order differential operators on graphs

    Författare :Jacob Muller; Pavel Kurasov; Ram Band; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Almost periodic functions; differential operators on metric graphs; quantum graphs; estimation of eigenvalues;

    Sammanfattning : This thesis consists of two papers, enumerated by Roman numerals. The main focus is on the spectral theory of -Laplacians. Here, an -Laplacian, for integer , refers to a metric graph equipped with a differential operator whose differential expression is the -th derivative. LÄS MER
