  4. 2. Problems in Number Theory related to Mathematical Physics

    Author : Rikard Olofsson; Pär Kurlberg; Nalini Anantharaman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; number theory; mathetical physics; local zeta functions; cat maps; Beurling primes; MATHEMATICS; MATEMATIK;

    Abstract : This thesis consists of an introduction and four papers. All four papers are devoted to problems in Number Theory. In Paper I, a special class of local ζ-functions is studied. The main theorem states that the functions have all zeros on the line Re(s)=1/2. READ MORE

  5. 3. Analytic and data-driven methods for 3D electron microscopy

    Author : Gustav Zickert; Pär Kurlberg; Ozan Öktem; Timo Koski; Roy Lederman; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The central theme of this thesis is theoretical and algorithmic aspects of 3D electron microscopy (3D-EM). In particular, the thesis explores three parts of this theme. The first part concerns analysis of forward operators that, compared to those traditionally used, better account for the wave properties of the imaging electron. READ MORE
