  • Moldestad, Johan; Normann, Dag (Research report / Forskningsrapport, 1974)
  • Jahren, Bjørn; Kwasik, Slawomir (Research report / Forskningsrapport, 2000)
  • De Poi, Pietro (Research report / Forskningsrapport, 2001)
    In this article we classify all the smooth 3-folds of P5 with an apparent 4-tuple point provided that the family of its 4-secant lines is an irreducible (first order) congruence. This is sufficient to conclude the ...
  • Lindbæck, Astri Strand (Master thesis / Masteroppgave, 2015)
    Punktene på en elliptisk kurve danner en gruppe. Hvis vi kaller origo i gruppa for Q, er et n-torsjonspunkt et punkt P som er slik at nP=Q. Mengden n-torsjonspunkter danner en abelsk gruppe. Alle 3-torsjonspunktene på en ...
  • Graff, Michael (Master thesis / Masteroppgave, 2014)
    The Icelandic population is scarce compared to the Norwegian, causing high variability in the observed mortalities. We apply two mortality models to data on the Norwegian population dating 60 years back, and the Icelandic ...
  • Shaw, Kristin; Brugallé, Erwan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)
    This friendly introduction to tropical geometry is meant to be accessible to first year students in mathematics. The topics discussed here are basic tropical algebra, tropical plane curves, some tropical intersections, and ...
  • Corcuera, José Manuel; Di Nunno, Giulia; Farkas, Gergely; Øksendal, Bernt (Research report / Forskningsrapport, 2014)
  • Chatterjee, Neelabja; Fjordholm, Ulrik Skre (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We derive and study a Lax–Friedrichs-type finite volume method for a large class of nonlocal continuity equations in multiple dimensions. We prove that the method converges weakly to the measure-valued solution and converges ...
  • Ottem, John Christian; Rennemo, Jørgen Vold (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The Grassmannian Gr(2,5) is embedded in ℙ9 via the Pl\"ucker embedding. The intersection of two general PGL(10)-translates of Gr(2,5) is a Calabi-Yau 3-fold X, and the intersection of the projective duals of the two ...
  • Neshveyev, Sergey; Yamashita, Makoto (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We prove two results on the tube algebras of rigid C*-tensor categories. The first is that the tube algebra of the representation category of a compact quantum group G is a full corner of the Drinfeld double of G. As an ...
  • Ravi, Charanya (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    We prove a Grothendieck–Lefschetz theorem for equivariant Picard groups of non-singular varieties with finite group actions.
  • Crisan, Dan; Ortiz-Latorre, Salvador (Journal article / Tidsskriftartikkel / SubmittedVersion, 2013)
    The aim of this paper is to introduce a new numerical algorithm for solving the continuous time nonlinear filtering problem. In particular, we present a particle filter that combines the Kusuoka–Lyons–Victoir (KLV) cubature ...
  • Benth, Fred Espen (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The recent introduction of wind power futures written on the German wind power production index has brought with it new interesting challenges in terms of modelling and pricing. Some particularities of this product are the ...
  • Fornæss, John Erik; Wold, Erlend Fornæss (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
  • Volkmann, Alexander; De Bin, Riccardo; Sauerbrei, Willi; Boulesteix, Anne-Laure (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Background: Omics data can be very informative in survival analysis and may improve the prognostic ability of classical models based on clinical risk factors for various diseases, for example breast cancer. Recent research ...
  • Benth, Fred Espen; Ortiz-Latorre, Salvador (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    In electricity markets, it is sensible to use a two-factor model with mean reversion for spot prices. One of the factors is an Ornstein–Uhlenbeck (OU) process driven by a Brownian motion and accounts for the small variations. ...
  • Aamodt, Geir; Samuelsen, Sven O; Skrondal, Anders (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2006)
    Background Cluster detection is an important part of spatial epidemiology because it can help identifying environmental factors associated with disease and thus guide investigation of the aetiology of ...
  • Riiser, Even Sannes; Haverkamp, Thomas Hendricus Augustus; Borgan, Ørnulf; Jakobsen, Kjetill Sigurd; Jentoft, Sissel; Star, Bastiaan (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Atlantic cod (Gadus morhua) provides an interesting species for the study of host-microbe interactions because it lacks the MHC II complex that is involved in the presentation of extracellular pathogens. Nonetheless, little ...
  • Tøstesen, Eivind (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2008)
    Background It is of biological interest to make genome-wide predictions of the locations of DNA melting bubbles using statistical mechanics models. Computationally, this poses the challenge that a generic ...
