    • Non-standard shocks in the Buckley-Leverett equation 

      Kalisch, Henrik; Mitrovic, Darko; Nordbotten, Jan Martin (Peer reviewed; Journal article, 2015-08)
      It is shown how delta shock waves which consist of Dirac delta distributions and classical shocks can be used to construct non-monotone solutions of the Buckley–Leverett equation. These solutions are interpreted using a ...

    • Trigonometric interpolation on lattice grids 

      Sørevik, Tor; Nome, Morten (Peer reviewed; Journal article, 2015)
      In this paper we construct non-aliasing interpolation spaces and Lagrange functions for lattice grids. We argue that lattice grids are good for trigonometric interpolation and support this claim by numerical experiments. ...
