(Research report / Forskningsrapport, 2005)We introduce the notion of a Galois extension of commutative S-algebras (E∞ ring spectra), often localized with respect to a fixed homology theory. There are numerous examples, including some involving Eilenberg-Mac Lane ...
-
(Master thesis / Masteroppgave, 2015)In 1862, substituting for professor O. J. Broch, Ludvig Sylow gives the first lectures ever given on the field of Galois theory in Norway, at the University of Christiania. He lectures on, amongst other things, what he ...

(Master thesis / Masteroppgave, 2022)Målet med denne oppgaven er å utforske og kategorisere et utvalg av ringer fra ringspillet. Ringspillet er et upartisk kombinatorisk spill. I det første kapittelet, vil vi gå gjennom litt grunnleggende teori om ringer. I ...

(Research report / Forskningsrapport, 2006)We consider a stochastic differential game in a financial jump diffusion market, where the agent chooses a portfolio which maximizes the utility of her terminal wealth, while the market chooses a scenario (represented by ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Multiphase flow simulations were run in OpenFOAM utilizing InterFoam, a volume of fluid type solver. A concentric annulus geometry was constructed and periodic boundary conditions were applied to alleviate the requirement ...
-
(Research report / Forskningsrapport, 2009)We propose a method to compute approximate eigenpairs of the Schrödinger operator on a bounded domain in the presence of an electromagnetic field. The method is formulated for the simplicial grids that satisfy the discrete ...

(Research report / Forskningsrapport, 2010)In this paper, we develop a variational approach to study perturbation problems of ordinary differential equations (ODE's) with discontinuous coefficients. We propose a mathematical framework which can be used to construct ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)We introduce here the idea of a long-term swap rate, characterized as the fair rate of an overnight indexed swap (OIS) with infinitely many exchanges. Furthermore, we analyze the relationship between the long-term swap ...

A general maximum principle for anticipative stochastic control and applications to insider trading (Research report / Forskningsrapport, 2009)In this paper we suggest a general stochastic maximum principle for optimal control of anticipating stochastic differential equations driven by a Lévy type of noise. We use techniques of Malliavin calculus and forward ...

-
(Master thesis / Masteroppgave, 2016)A detailed study of computable iterations of Gödel-sentences, both in normal recursion and generalisations to other recursive theories.

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)We provide both a general framework for discretizing de Rham sequences of differential forms of high regularity, and some examples of finite element spaces that fit in the framework. The general framework is an extension ...
