(Master thesis / Masteroppgave, 2021)Building upon recent work by Binda, Park, and Østvær we construct a theory of motives with compact support in the setting of logarithmic algebraic geometry. Starting from the notion of finite logarithmic correspondences ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Inspired by Bhatt–Morrow–Scholze’s work on THH, we define Nygaard-completed log prismatic cohomology based on log topological Hochschild homology via filtrations on log THH and its variants. Moreover, of independent ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)In this paper we continue our study of logarithmic topological Hochschild homology. We show that the inclusion of the connective Adams summand ℓ into the p-local complex connective K-theory spectrum ku(p), equipped with ...

(Research report / Forskningsrapport, 2008)In this paper we will approximate the sum of the margins from a two dimensional lognormal variable by moment matching with a one dimensional lognormal variable. We will look at different cases of correlation and volatility ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Objective A number of observational studies have shown an inverse association between circulating 25-hydroxyvitamin D and total mortality, but a reverse J-shaped association has also been reported. In a large nested ...

Long wave generation and coastal amplification due to propagating atmospheric pressure disturbances (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Abstract Meteotsunamis are long waves generated by displacement of a water body due to atmospheric pressure disturbances that have similar spatial and temporal characteristics to landslide tsunamis. NAMI DANCE that solves ...
-
(Master thesis / Masteroppgave, 2017)In this thesis results from numerical simulations of long wave run-up on composite beaches are presented along with the analytical solution to the linear problem. The purpose of this study is to find out which parts of the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)Background Sleep is important for healthy functioning in children. Numerous genetic and environmental factors, from conception onwards, may influence this phenotype. Epigenetic mechanisms such as DNA ...

-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2024)The present paper investigates Cox-Ingersoll-Ross (CIR) processes of dimension less than 1, with a focus on obtaining an equation of a new type including local times for the square root of the CIR process. To derive this ...

(Research report / Forskningsrapport, 2008)In a continuous time market model we consider the problem of existence of an equivalent martingale measure with density lying within given lower and upper bounds and we characterize a necessary and sufficient condition for ...
-
(Research report / Forskningsrapport, 2002)Second order effects of axial forces on displacements in compression members are small and can be neglected in a great many structures, which may then be designed for forces obtained by conventional first order theory. ...
-
(Research report / Forskningsrapport, 2002)Effects of axial forces on the displacements in compression members, generally termed second order effects, are small and can be neglected in a great many structures. In recognition of this, most design codes and standards ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2006)Starting with a problem in wireless telecommunication, we are led to study the multiple knapsack problem with assignment restrictions. This problem is NP-hard. We consider special cases and their computational complexity. ...

(Research report / Forskningsrapport, 2003)We propose a Kruzkov-type entropy condition for nonlinear degenerate parabolic equations with discointinuous coefficients. We establish L1 stability, and thus uniqueness, for weak solutions satisfying the entropy condition, ...
