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 ... -
Å estimere feilrater for periodisk testede flertilstandssystemer med sovende feil: I et bayesiansk rammeverk med Markov chain Monte Carlo-metoder
(Master thesis, 2009)Denne rapporten fra masteroppgaven på Industriell matematikk handler om å estimere feilrater for periodisk testede flertilstandssystemer med sovende feil. Dette gjøres i et bayesiansk rammeverk ved hjelp av Markov chain ... -
α -Modulation Spaces for Step Two Stratified Lie Groups
(Journal article; Peer reviewed, 2022)We define and investigate α-modulation spaces Ms,α p,q(G) associated to a step two stratified Lie group G with rational structure constants. This is an extension of the Euclidean α-modulation spaces Ms,α p,q(Rn) that act ... -
τ-PERPENDICULAR WIDE SUBCATEGORIES
(Journal article; Peer reviewed, 2023)Let Λ be a finite-dimensional algebra. A wide subcategory of modΛ is called left finite if the smallest torsion class containing it is functorially finite. In this article, we prove that the wide subcategories of modΛ ...
