Non-standard shocks in the Buckley-Leverett equation
(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
(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. ...
