  1. 1. Ramification points of parameterized second-order polynomials and determination of zeros of generalized trigonometric and cylindrical polynomials

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för elektroteknik, matematik och naturvetenskap

    Författare :Davide Mariotti; [2020]
    Nyckelord :ramification points; cylindrical polynomials; perturbations;

    Sammanfattning : We consider the parameter dependence of zeros of polynomials and particularly the properties of the ramication points of second-order (quadratic) polynomials. The results are applied to the analysis of real and complex zeros of a particular set of generalized cylindrical polynomials in order to study resonance scattering of electromagnetic waves by a circular dielectric cylinder.

  3. 2. Att gestalta en mördare : En studie om mediernas gestaltning av Thomas Quick

    Kandidat-uppsats, Karlstads universitet/Institutionen för geografi, medier och kommunikation

    Författare :Viktoria Nilsson; Emma Båld; [2015]
    Nyckelord :mediepåverkan; attribut; Thomas Quick; mediegestaltning; medier och brott;

    Sammanfattning : Media has a big actuating power over the public opinion. The image of reality that media choose to reproduce will affect the recipient view of reality. The case about Thomas Quick and its associated news coverage has been used as an example to illustrate the problematization regarding media imag-es and media framing attempt. LÄS MER

  4. 3. Lower ramification numbers of wildly ramified power series

    Magister-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Jonas Fransson; [2014]
    Nyckelord :Lower ramification numbers; Minimal ramification; Ramified polynomials; Ramified power series; Difference equations; Recurrence relations; Optimal cycles; Periodic points;

    Sammanfattning : In this thesis we study lower ramification numbers of power series tan- gent to the identity that are defined over fields of positive characteristics. Let f be such a series, then f has a fixed point at the origin and the corresponding lower ramification numbers of f are then, up to a constant, the multiplicity of zero as a fixed point of iterates of f.

  5. 4. Algebraic Curves over Finite Fields

    Master-uppsats, Matematiska institutionen

    Författare :Carmen Rovi; [2010]
    Nyckelord :Nullstellensatz; variety; rational function; Function field; Weierstrass gap Theorem; Ramification; Hurwitz genus formula; Kummer and Artin-Schreier extensions; Hasse-Weil bound; Goppa codes.;

    Sammanfattning : This thesis surveys the issue of finding rational points on algebraic curves over finite fields. Since Goppa's construction of algebraic geometric codes, there has been great interest in finding curves with many rational points. LÄS MER
