Waves of maximal height for a class of nonlocal equations with homogeneous symbols
(Peer reviewed; Journal article, 2021)We discuss the existence and regularity of periodic traveling-wave solutions of a class of nonlocal equations with homogeneous symbol of order −r , where r > 1. Based on the properties of the nonlocal convolution operator, ... -
Weighted approximation in C
(Journal article; Peer reviewed, 2019)We prove that if {φj}j is a sequence of subharmonic functions which are increasing to some subharmonic function φ in C , then the union of all the weighted Hilbert spaces H(φj) is dense in the weighted Hilbert ... -
Well-Posedness of a Fractional Mean Field Game System with Non-Local Coupling
(Master thesis, 2017)We prove existence and uniqueness of classical solutions for a fractional Mean Field Game system with non-local coupling, where the fractional exponent is greater than 1/2. To our knowledge this is not proven before in ... -
Wettability Index for Reservoir Simulation and History Matching Core Displacement Experiments
(Master thesis, 2008)A fully coupled formulation for three-phase capillary pressure and relative permeability, the flow parameters, with hysteresis and miscibility capabilities have been established. This work presents an extension to this ... -
What can observational data reveal about metacommunity processes?
(Peer reviewed; Journal article, 2019)A key challenge for community ecology is to understand to what extent observational data can be used to infer the underlying community assembly processes. As different processes can lead to similar or even identical patterns, ... -
What is a post-Lie algebra and why is useful in geometric integration
(Journal article; Peer reviewed, 2018)We explain the notion of a post-Lie algebra and outline its role in the theory of Lie group integrators. -
Whole-genome sequencing analysis of the cardiometabolic proteome
(Journal article; Peer reviewed, 2020)The human proteome is a crucial intermediate between complex diseases and their genetic and environmental components, and an important source of drug development targets and biomarkers. Here, we comprehensively assess the ... -
Wick polynomials in non-commutative probability: A group-theoretical approach
(Journal article; Peer reviewed, 2021) -
A Wiener Tauberian theorem for operators and functions
(Peer reviewed; Journal article, 2021)We prove variants of Wiener's Tauberian theorem in the framework of quantum harmonic analysis, i.e. for convolutions between an absolutely integrable function and a trace class operator, or of two trace class operators. ... -
Workflow for Sensitivity Analysis and Decision Making on the Lower Limit of the Mud-Weight Window in an Overpressured Formation
(Peer reviewed; Journal article, 2020)When drilling a well it is important to choose a reasonable mud density to ensure safe operations. This is not a trivial task because a balanced mud-weight has a complex relation to the uncertain formation conditions and ... -
Workshop on classroom research: Analysis of transcript data
(Chapter, 2007)This paper is a report of the workshop initiated by the Nordic Graduate School inMathematics Education. The paper focuses especially on the decisions taken in the planning of the workshop and how the plans were implemented. ... -
Yang-Mills connections on quantum Heisenberg manifolds
(Journal article; Peer reviewed, 2020)We investigate critical points and minimizers of the Yang-Mills functional YM on quantum Heisenberg manifolds Dc µν, where the Yang-Mills functional is defined on the set of all compatible linear connections on finitely ... -
You Just Keep on Pushing My Love over the Borderline: A Rejoinder
(Journal article; Peer reviewed, 2017)The entire reason that we wrote this paper was to provide a concrete object around which to focus a broader discussion about prior choice and we are extremely grateful to the editorial team at Statistical Science for this ... -
Yrkesfagelevar og matematikk - Ein studie av elevar på Bygg- og Anleggsteknikk sine haldningar til matematikkfaget, og deira matematiske forståing av yrkesretta og tradisjonell matematikk
(Master thesis, 2018)Målet med denne masteroppgåva er å kartleggje kva for samanheng det er mellom elevar på studieprogrammet Bygg- og Anleggsteknikk sine haldningar til matematikk og deira matematiske forståing av matematikk i ulike kontekstar. ... -
Zappa-Szép products for partial actions of groupoids on left cancellative small categories
(Peer reviewed; Journal article, 2022)We study groupoid actions on left cancellative small categories and their associated Zappa-Sz´ep products. We show that certain left cancellative small categories with nice length functions can be seen as Zappa-Sz´ep ... -
Zd-odometers and cohomology
(Journal article; Peer reviewed, 2019)Cohomology for actions of free abelian groups on the Cantor set has (when endowed with an order structure) provided a complete invariant for orbit equivalence. In this paper, we study a particular class of actions of such ... -
Zero-Knowledge Protocols for proof of Correct Shuffle using Lattices
(Master thesis, 2022)Hovedformålet med denne oppgaven er å studere protokoller for kunskapsløse bevis av korrekt ommstokning ved bruk av gitter. For å forstå utregningene gjort i protkollene og hvorfor protokollene er sikre, har vi dedikert ... -
Zeroing the Output of Nonlinear Systems Without Relative Degree
(Book, 2023)The goal of this paper is to establish some facts concerning the problem of zeroing the output of an input-output system that does not have relative degree. The approach taken is to work with systems that have Chen-Fliess ... -

Zeros of the Wigner distribution and the short-time Fourier transform
(Peer reviewed; Journal article, 2019)We study the question under which conditions the zero set of a (cross-) Wigner distribution W(f, g) or a short-time Fourier transform is empty. This is the case when both f and g are generalized Gaussians, but we will ...
