(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Observations of wave propagation in landfast ice were obtained in Tempelfjorden, Svalbard during March 2015. Wave motion was measured near the ice edge using inertial motion units and consisted of a combination of swell ...

(Research report / Forskningsrapport, 1999)The extended version of this article was published in Ukrainian Mathematical Journal, 2009, vol 61(12), doi:10.1007/s11253-010-0324-8. https://doi.org/10.1007/s11253-010-0324-8

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)We provide some new local obstructions to approximating tropical curves in smooth tropical surfaces. These obstructions are based on a relation between tropical and complex intersection theories, which is also established ...

(Master thesis / Masteroppgave, 2012)Til enhver kvatratisk (reel eller kompleks) matrise A kan man tilordne dens eksponentialmatrise e^{At}. Eksponentialmatriser spiller en viktig rolle ved løsningen av enkelte differensialligninger og i mange andre anvendelser. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)In this work we investigate the long-time behavior for Markov processes obtained as the unique mild solution to stochastic partial differential equations in a Hilbert space. We analyze the existence and characterization ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)In this paper we discuss a conjecture of Schumaker that the principal submatrices of collocation matrices of bivariate Bernstein polynomials over triangular grids have positive determinant. It is easy to show that the ...

(Research report / Forskningsrapport, 2003)The well-known Lighthill-Whitham-Richards kinematic traffic flow model for unidirectional flow on a single-lane highway is extended to include both abruptly changing road surface conditions and drivers' reaction time and ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We introduce a rough perturbation of the Navier–Stokes system and justify its physical relevance from balance of momentum and conservation of circulation in the inviscid limit. We present a framework for a well-posedness ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)The problem on identification of a limit of an ordinary differential equation with discontinuous drift that perturbed by a zero-noise is considered in multidimensional case. This problem is a classical subject of stochastic ...

(Research report / Forskningsrapport, 2006)We consider a fully parabolic model for chemotaxis with volume-filling effect and a nonlinear diffusion that degenerates in a two-sided fashion. We address the questions of existence of weak solutions and of their regularity ...
