      Knutsen, Andreas Leopold (Journal article; Peer reviewed, 2020)
      Let S⊂Pg be a smooth K3 surface of degree 2g−2, g≥3. We classify all the cases for which h0(NS/Pg(−2))≠0 and the cases for which h0(NS/Pg(−2))<h0(NC/Pg−1(−2)) for C⊂Pg−1 a general canonical curve section of S.

    • Gonality of Points in Brill-Noether Loci of the Moduli Space of Curves 

      Sæbø, Gard (Master thesis, 2012-05-31)
      In this masterthesis we study the geometry of the points in the Brill-Noether locus. Typically, we want to study the gonality of points in this locus, that can be seen as projective curves. We also study what curves on ...
    • Good ethics or political and cultural censoring in science? 

      Torrissen, Ole; Glover, Kevin; Haug, tore; Misund, Ole Arve; Skaug, Hans J.; Kaiser, Matthias (Peer reviewed; Journal article, 2012)
      Peer-reviewed journals are the cornerstones to communicating scientific results. They play a crucial role in quality assurance through the review process, but they also create opportunities for discussions in the scientific ...
    • Gradient Methods for Source Identification Problems 

      Banshoya, Shin Irgens (Master thesis, 2020-08-19)
      In this thesis we are interested in the problem of identifying point sources in an advection-diffusion model, given some measurements. By writing the problem as a minimization problem, we use a non-linear conjugate gradient ...

      Bethuelsen, Stein Andreas; Valesin, Daniel; Baptista da Silva, Gabriel (Journal article; Peer reviewed, 2021)
      We construct graphs (trees of bounded degree) on which the contact process has critical rate (which will be the same for both global and local survival) equal to any prescribed value between zero and λc(Z), the critical ...
