Triangulated Derivators and their Calabi-Yau Dimension
(Master thesis, 2021)Vi introduserer teorien bak derivatorer fra perspektivet til homologisk algebra. Først med motivasjon fra deriverte kategorier og kanutvidelser, deretter en nøye gjennomgang av teorien. Vi utvider flere resultater fra ... -
Triangulated structure of stable Frobenius categories and derived abelian categories
(Bachelor thesis, 2024)Triangulære kategorier er et av hovedområdene innenfor homologisk algebra, spesielt gitt at er opptil flere viktige kategoriske strukturer som oppstår i nærliggende fagfelt som kan ses på med en triangulær struktur. Stabile ... -
Trimodal Steady Water Waves
(Journal article, 2014)We construct three-dimensional families of small-amplitude gravity-driven rotational steady water waves on finite depth. The solutions contain counter-currents and multiple crests in each minimal period. Each such wave ... -
Tropical time series, iterated-sums signatures and quasisymmetric functions

Turbulence characterisation in complex fjord topography using measurement and numerical modelling for bridge design
(Doctoral theses at NTNU;2022:88, Doctoral thesis, 2022)On Norway’s west coast, the Norwegian Public Road Administration initiated a major infrastructure development project that includes the design and construction of bridges to replace ferries. The width of the fjords, flow ... -
Twenty-three unsolved problems in hydrology (UPH) – a community perspective
(Journal article; Peer reviewed, 2019)This paper is the outcome of a community initiative to identify major unsolved scientific problems in hydrology motivated by a need for stronger harmonisation of research efforts. The procedure involved a public consultation ... -
TWG1: Transitions to, across and from University Mathematics
(Journal article; Peer reviewed, 2023) -
Twisted Convolution Algebras and Applications to Gabor Analysis
(Doctoral theses at NTNU;2021:155, Doctoral thesis, 2021)This thesis concerns several aspects of twisted convolution algebras, with a particular focus on problems arising in Gabor analysis. A significant portion of the thesis is dedicated to the study of Hilbert C -modules known ... -
Two classes of quadratic vector fields for which the Kahan discretization is integrable

Two results in Harmonic analysis and PDEs
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:170, Doctoral thesis, 2014) -
Two types of Rubio de Francia operators on Triebel-Lizorkin and Besov spaces
(Peer reviewed; Journal article, 2018)We discuss generalizations of Rubio de Francia’s inequality for Triebel–Lizorkin and Besov spaces, continuing the research from Osipov (Sb Math 205(7): 1004–1023, 2014) and answering Havin’s question to one of the authors. ... -
Two Weight Discrete Hilbert Transforms and Systems of Reproducing Kernels
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:124, Doctoral thesis, 2011)The Hilbert transform has become increasingly popular over the years due to its wide ranging applications not only in mathematics, but also in many other applied areas. In a quest for more applications, studying various ... -
Two-dimensional simulation methods for offshore wind turbines

Two-scale topology optimization with heterogeneous mesostructures based on a local volume constraint
(Peer reviewed; Journal article, 2022)A new approach to produce optimal porous mesostructures and at the same time optimizing the macro structure subject to a compliance cost functional is presented. It is based on a phase-field formulation of topology ... -
Two-sided p-values for a non-symmetric distribution of test statistics
(Bachelor thesis, 2022)I denne oppgaven undersøkes ulike måter å beregne p-verdier for en tosidig hypotesetest hvor testobservatoren har en usymmetrisk sannsynlighetsfordeling. Først gis en kort introduksjon til statistiske begreper før Fishers ... -
Two-variable fibrations, factorisation systems and -categories of spans
(Peer reviewed; Journal article, 2023)We prove a universal property for ∞-categories of spans in the generality of Barwick’s adequate triples, explicitly describe the cocartesian fibration corresponding to the span functor, and show that the latter restricts ... -
Ultraprodukter og anvendelser i kommutativ algebra
(Bachelor thesis, 2024)Denne oppgaven gir en introduksjon til ultraprodukter, med sikte for å gjøre algebra med dem. Ultraproduktet, en konstruksjon fra modellteorien, er et slags gjennomsnitt av objektene det tar inn: Et ultraprodukt av ringer ... -
Unbounded HIBE with Tight Security
(Peer reviewed; Journal article, 2020)We propose the first tightly secure and unbounded hierarchical identity-based encryption (HIBE) scheme based on standard assumptions. Our main technical contribution is a novel proof strategy that allows us to tightly ... -
