• #### Non-commutative Harmonic Analysis: Generalization of Phase Correlation to the Euclidean Motion Group ﻿

(Master thesis, 2010-06-10)
This thesis is about noncommutative harmonic analysis, and generalization of phase correlation to the euclidean motion group and application in image processing.
• #### Non-Slit Solutions to the Loewner Equation ﻿

(Master thesis, 2010-04-30)
We study conditions on the driving term of the Loewner equation which guarantee that the equation generates slits. We construct a new family of examples of non-slit solutions which generalize Kufarev's example, in which ...
• #### 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 ...
• #### Nonholonomic geometry on finite and infinite dimensional Lie groups and rolling manifolds ﻿

(Doctoral thesis, 2012-03-30)
Part I: We start by giving some background on the topics discussed in this thesis. The main topic of the thesis is nonholonomic geometry. In Chapter 1 we give an introduction of nonholonomic geometry in the context of ...
• #### Nonhydrostatic pressure in ocean models with focus on wind driven internal waves ﻿

(Doctoral thesis, 2010-02-05)
• #### Nonlinear cross-spectrum analysis via the local Gaussian correlation ﻿

(Journal article, 2017)
Spectrum analysis can detect frequency related structures in a time series $\{Y_t\}_{t\in\mathbb{Z}}$, but may in general be an inadequate tool if asymmetries or other nonlinear phenomena are present. This limitation is ...

• #### Nonlinear spectral analysis via the local Gaussian correlation ﻿

(Journal article, 2017)
The spectral distribution $f(\omega)$ of a stationary time series $\{Y_t\}_{t\in\mathbb{Z}}$ can be used to investigate whether or not periodic structures are present in $\{Y_t\}_{t\in\mathbb{Z}}$, but $f(\omega)$ ...
• #### Nonlinear Spectrum Analysis based on the Local Gaussian Correlation and Model Selection for Copulas ﻿

(Doctoral thesis, 2017-11-20)
• #### The Norwegian Stock Market: - A Local Gaussian Perspective ﻿

(Master thesis, 2013-06-03)
In this thesis, using daily returns from 18 stocks, oil price, exchange rates and the main index of the Oslo Stock Exchange over a period of 5 years, we investigate how the Local Gaussian Correlation can be used to describe ...

• #### A note on Severi varieties of nodal curves on Enriques surfaces ﻿

(Journal article; Peer reviewed, 2020)
Let |L| be a linear system on a smooth complex Enriques surface S whose general member is a smooth and irreducible curve of genus p, with L2 > 0, and let V|L|,δ(S) be the Severi variety of irreducible δ-nodal curves in ...
