Categorial Independence and Lévy Processes
(Journal article; Peer reviewed, 2022) -
Categorical matrix factorizations
(Peer reviewed; Journal article, 2023) -
Categorification and the quantum Grassmannian
(Peer reviewed; Journal article, 2022) -
The category of extensions and a characterisation of n-exangulated functors
(Peer reviewed; Journal article, 2023)Additive categories play a fundamental role in mathematics and related disciplines. Given an additive category equipped with a biadditive functor, one can construct its category of extensions, which encodes important ... -
A category of wide subcategories
(Journal article; Peer reviewed, 2021) -
Catlin's boundary systems for sums of squares domains
(Peer reviewed; Journal article, 2023)For any given sum of squares domain in Cn , we reduce the complexity in Catlin's multitype techniques by giving a complete normalization of the geometry. Using this normalization result, we present a more elementary proof ... -
Censored Weibull Distributed Data in Experimental Design
(Master thesis, 2014)Give an introduction to experimental design. Investigate how four methods handle Weibull distributed censored data, where the four methods are the quick and dirty method, the maximum likelihood method, single imputation ... -
Challenges and motivation for teachers transitioning to active learning spaces
(Peer reviewed; Journal article, 2023)Research indicates that active learning and Active Learning Spaces (ALSs) may improve student learning. Four teachers in mathematics and statistics at a Norwegian university are examined as they transition to ALSs. The ... -
Change of rings and singularity categories
(Journal article, 2019)We investigate the behavior of singularity categories and stable categories of Gorenstein projective modules along a morphism of rings. The natural context to approach the problem is via change of rings, that is, the ... -
Changepoint model selection in Gaussian data by maximization of approximate Bayes Factors with the Pruned Exact Linear Time algorithm
(Master thesis, 2018)In this thesis we consider the changepoint detection in independently distributed Gaussian data. Detection of multiple changepoints in a data set is treated as a model selection problem where the model complexity is ... -
Changepoint Models
(Master thesis, 2009)In this thesis we study recursion methods for making Bayesian inference on a class of multiple changepoint models, introduced in Fearnhead(2006). We present and implement recursion algorithms, and we evaluate how parameter ... -
Characteristics of temporal changes in communities where dynamics differ between species
(Journal article; Peer reviewed, 2016)Communities with different phenotypic variation among species can have identical species abundance distributions, although their temporal dynamics may be very different. By using stochastic species abundance models, both ... -
Characterization and boundary behavior of harmonic functions in growth spaces
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:227, Doctoral thesis, 2013) -
Characterizing changes of dissolved organic matter composition with the use of distinct feeds in recirculating aquaculture systems via high-resolution mass spectrometry
(Peer reviewed; Journal article, 2020)Recirculating aquaculture systems (RAS) are a new alternative to traditional aquaculture approaches, allowing full control over the fish production conditions, while reducing the water demand. The reduction of water exchange ... -
Chlamydia trachomatis infections in Norway 2004-2006: Testing and treatment patterns among men and women
(Master thesis, 2009)Background: In Norway, the number of positive tests for Chlamydia Trachomatis (CT) is increasing. Patients with a positive CT test result should be immediately treated with oral antibiotics according to the treatment ... -
Choice of representations in combinatorial problems
(Chapter, 2022)This paper is based on classroom sessions where Norwegian 9-year-old (Grade 4) children work on combinatorial problems. The classroom sessions are part of a four-year long research project where the topic of multiplicative ... -
Chopsticks: Fork-Free Two-Round Multi-signatures from Non-interactive Assumptions
(Peer reviewed; Journal article, 2023)Multi-signatures have been drawing lots of attention in recent years, due to their applications in cryptocurrencies. Most early constructions require three-round signing, and recent constructions have managed to reduce the ... -
Circulating microRNAs as predictive biomarkers of myocardial infarction: Evidence from the HUNT study.
(Peer reviewed; Journal article, 2019)Background and aims Several risk prediction models for coronary heart disease (CHD) are available today, however, they only explain a modest proportion of the incidence. Circulating microRNAs (miRs) have recently been ... -
Classical well-posedness in dispersive equations with nonlinearities of mild regularity, and a composition theorem in Besov spaces
(Journal article; Peer reviewed, 2018)For both localized and periodic initial data, we prove local existence in classical energy space Hs,s > 3 2 , for a class of dispersive equations ut +(n(u))x +Lux = 0 with nonlinearities of mild regularity. Our results are ...
