    • Zappa-Szép products for partial actions of groupoids on left cancellative small categories 

      Pardo, E; Ortega Esparza, Eduardo (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 

      Giordano, Thierry; Putnam, Ian F.; Skau, Christian Fredrik (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 

      Edstrøm, Ole Martin (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 

      Ebrahimi-Fard, Kurusch; Gray, W. Steven; Schmeding, Alexander (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 ...
    • Zeroing the Output of Nonlinear Systems Without Relative Degree 

      Gray, W. Steven; Ebrahimi-Fard, Kurusch; Schmeding, Alexander (Chapter, 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 

      Grochenig, Karlheinz; Jaming, Philippe; Malinnikova, Eugenia (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 

      Bjørkli, Ingrid (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 

      Berge, Eirik (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 

      Buan, Aslak Bakke; Hanson, Eric J. (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 ...
