Linear functions and duality on the infinite polytorus
(Journal article; Peer reviewed, 2019)We consider the following question: are there exponents 22 . Our approach is based on duality arguments and a detailed study of linear functions. Some related results are also presented. -
Linear Regression for Survey Data
(Bachelor thesis, 2020)Denne bacheloroppgaven er en del av emnet MA2002 på NTNU, som er 15 studiepoeng over ett semester. I denne oppgaven diskuterer vi hvordan man gjør linear regresjon når et komplekst utvalgsdesign er brukt for å samle inn ... -
Linear space properties of H^p spaces of Dirichlet series
(Journal article; Peer reviewed, 2019)We study H p spaces of Dirichlet series, called H p , for the range 0 < p < ∞. We begin by showing that two natural ways to define H p coincide. We then proceed to study some linear space properties of H p . More specifically, ... -
Linearization of Hénon maps and a polynomial automorphism with wandering Fatou components
(Doctoral theses at NTNU;2018:308, Doctoral thesis, 2018) -
Linearized Difference Networks as Approximate Kernel Methods
(Master thesis, 2019)I denne artikkelen studerer vi nevrale nettverk som tilnærminger til en relatert kjerne-metode (kernel method). Vi analyserer forutsigelsene gjort av et enkelt nevralt nettverk med et skjult lag. To kilder til varians i ... -
Linearly implicit local and global energy-preserving methods for Hamiltonian PDEs
(Journal article, 2019)We present linearly implicit methods that preserve discrete approximations to local and global energy conservation laws for multi-symplectic PDEs with cubic invariants. The methods are tested on the one-dimensional Korteweg–de ... -
Linearly implicit structure-preserving schemes for Hamiltonian systems
(Journal article, 2019)Kahan’s method and a two-step generalization of the discrete gradient method are both linearly implicit methods that can preserve a modified energy for Hamiltonian systems with a cubic Hamiltonian. These methods are here ... -
Lineær mikset modell for kompressor data med en applikasjon
(Master thesis, 2008)StatoilHydro is the operator of the Åsgard oil and gas field outside of Trøndelag, Norway, where large compressors for injection, recompression and export of natural gas are installed. The facility transports and stores ... -
Lineære hemmelige delingsprotokoller og sikre flerpartsberegninger
(Master thesis, 2014)Vi ser på lineære hemmelige delingsprotokoller og sikre flerpartsberegningsprotokoller. Shamirs hemmelige delingsprotokoll og en hemmelig delingsprotokoll basert på monotone utspenningsprogram blir presentert. Vi ser også ... -
The Liouville theorem and linear operators satisfying the maximum principle.
(Peer reviewed; Journal article, 2020)A result by Courrège says that linear translation invariant operators satisfy the maximum principle if and only if they are of the form L = Lσ,b + Lμ where Lσ,b[u](x) = tr(σσTD2u(x)) + b · Du(x) and Lμ[u](x) = Rd\{0} u(x ... -

A Lipschitz metric for the Camassa--Holm equation
(Peer reviewed; Journal article, 2020)We analyze stability of conservative solutions of the Cauchy problem on the line for the Camassa–Holm (CH) equation. Generically, the solutions of the CH equation develop singularities with steep gradients while preserving ... -

(Journal article; Peer reviewed, 2012) -
Local Analysis of Ocean Wave Measurements
(Master thesis, 2007)This master thesis investigates the Short Time Fourier transform and the Continuous Wavelet transform in relation to a directional analysis of in situ ocean wave measurements. We have determined the statistical properties ... -
Local Class Field Theory via Lubin-Tate Formal Groups
(Bachelor thesis, 2023)Oppgaven tar for seg lokal klassekroppsteori via Lubin-Tate teori. Vi viser lokal samsvarighet, basebytte og eksistens for Lubin-Tate utvidelser. -
Local Gorenstein duality for cochains on spaces
(Peer reviewed; Journal article, 2021)We investigate when a commutative ring spectrum R satisfies a homotopical version of local Gorenstein duality, extending the notion previously studied by Greenlees. In order to do this, we prove an ascent theorem for local ... -
Logistic Mixed Models for Demographic and Health Indicators
(Master thesis, 2021)Nyfødtdødelighet og vaksinedekning mot meslinger er viktige helseindikatorer for en nasjon. Demographic and Health Surveys (DHS) er en pålitelig kilde for å spore indikatorer for å forbedre en nasjons helse i lav- og ... -
Long-Horizon Informative Path Planning with Obstacles and Time Constraints
(Peer reviewed; Journal article, 2022)We apply non-myopic informative path planning in a simulated river plume case study with several constraints on our agent. A cost valley philosophy is proposed to guide the agent through the field. The purpose of this path ...
