Koszul-algebraer over endelige kropper
(Master thesis, 2008)Vi har i denne masteroppgaven sett på Koszul-algebraer. Vi har definert Koszul-algebraer som graderte algebraer hvor de simple modulene har en lineær gradert projektiv oppløsning, og vi har bevist forskjellige karakteriseringer ... -
Koszul-algebraer over endelige kropper
(Master thesis, 2008)Masteroppgaven er innen algebra, nærmere bestemt Koszul-teori for algebraer. Koszul-algebraer, ble først definert av Priddy, har en sentral rolle innen algebra, geometri og topologi. Projektive moduler er viktige for å ... -
Krylov projection methods for linear Hamiltonian systems
(Journal article; Peer reviewed, 2019)We study geometric properties of Krylov projection methods for large and sparse linear Hamiltonian systems. We consider in particular energy-preservation. We discuss the connection to structure preserving model reduction. ... -
Krylov Subspace Accelerated Algebraic Multigrid for Mimetic Finite Differences on GPUs
(Master thesis, 2012)The topic of this thesis is GPU accelerated sparse linear algebra for subsurface reservoir modeling. Numerical techniques for reservoir sim- ulations are described and we present the open source reservoir simula- tion ... -
Krylovmetoder for lineære hamiltonske differensiallikninger
(Master thesis, 2016)Krylovmetoder er projeksjonsmetoder som kan transformere store lineære differensialligninger til mindre lineære differesialligninger med lignende egenskaper. To slike metoder (symplectic Lanczos method og Krylov projection ... -
Kunnskap om eksponentialfunksjonar gjennom tre læreplanverk for vidaregåande opplæring - Ein ATD-basert dokumentanalyse av læreplanar og lærebøker frå R94, LK06 og LK20
(Master thesis, 2022)Både i læreplanverket for Reform 94 (R94), i læreplanverket for Kunnskapsløftet 2006 (LK06) og i læreplanverket for Kunnskapsløftet (2020) inngår matematikklæreplanar for norsk vidaregåande opplæring som legg føringar for ... -
Kvasikonforme avbildninger og anvendelser i holomorf dynamikk
(Master thesis, 2007)Vi innfører klassen av kvasikonforme avbildninger i det komplekse planet, og viser en rekke fundamentale egenskaper ved disse. Herunder den målbare avbildningssatsen. Heretter anvendes disse resultatene til å vise ... -
L1 contraction for bounded (nonintegrable) solutions of degenerate parabolic equations
(Journal article; Peer reviewed, 2014-12-11)We obtain new L1 contraction results for bounded entropy solutions of Cauchy problems for degenerate parabolic equations. The equations we consider have possibly strongly degenerate local or nonlocal diffusion terms. As ... -
L1 semigroup generation for Fokker-Planck operators associated with general Levy driven SDEs
(Journal article; Peer reviewed, 2018)We prove a new generation result in L 1 for a large class of non-local operators with non-degenerate local terms. This class contains the operators appearing in Fokker-Planck or Kolmogorov forward equations associated ... -
De la TSD à la TAD. Un témoignage
(Journal article, 2021)L’intérêt actuel pour la théorie anthropologique du didactique (TAD) suscite, dans un grand nombre de pays du monde, un effort d’enseignement et d’apprentissage de la TAD. Tel est le fait cardinal qui fonde le projet de ... -
Lagrangian Relaxations for the Prize-Collecting Steiner Tree Problem
(Master thesis, 2013)In this thesis we look at the NP-hard Prize-Collecting Steiner Tree Problem (PCSTP). We show an application within biology, where the PCSTP is used to identify coregulated genes which are differently expressed for diffuse ... -
Land-use changes lead to functional loss of terrestrial mammals in a Neotropical rainforest
(Peer reviewed; Journal article, 2021)Land-use changes are a main driver of modifications in tropical ecosystems, leading to the loss of species and ecological traits and affecting key ecological functions. Although much attention has been given to predict the ... -
Landmark-guided elastic shape analysis of human character motions
(Journal article, 2017)Motions of virtual characters in movies or video games are typically generated by recording actors using motion capturing methods. Animations generated this way often need postprocessing, such as improving the periodicity ... -
Landscape relatedness: detecting contemporary fine-scale spatial structure in wild populations
(Journal article; Peer reviewed, 2016)Context: Methods for detecting contemporary, fine-scale population genetic structure in continuous populations are scarce. Yet such methods are vital for ecological and conservation studies, particularly under a changing ... -
Landwebers exact functor theorem
(Bachelor thesis, 2023)Når man jobber med algebraisk topologi bruker man mange invarianter. De er veldig viktige i fagfeltet. En slik invariant er kohomologi. Disse invariantene tar inn topologiske rom og sender ut abelske grupper. Med en passende ... -
Language elements helping to see enlargement as a multiplicative situation
(Chapter, 2020)This paper presents an analysis of Grade 5 pupils' work with similarity, based on an adaptation of Brousseau's classical puzzle. My main interest is in investigating the pupils' language repertoire and mathematical strategies ... -
Large greatest common divisor sums and extreme values of the Riemann zeta function

A large scale approach to decomposition spaces
(Peer reviewed; Journal article, 2022)Decomposition spaces are a class of function spaces constructed out of “well-behaved” coverings and partitions of unity of a set. The structure of the covering determines the properties of the decomposition space. Besov ... -
Large Scale Tertiary CO2 EOR in Mature Water Flooded Norwegian Oil Fields
(Journal article; Peer reviewed, 2017)A technical-economical model for a large-scale infrastructure combining CO2 EOR and aquifer storage has been used to construct a scenario including 23 Norwegian Continental Shelf oil fields that have been identified as ...
