Ample Groupoids and their Topological Full Groups
Nyland, Petter Kjeverud (Doctoral theses at NTNU;2020:292, Doctoral thesis, 2020)In this thesis we study the topological full group of an ample groupoid, with a particular focus on groupoids arising from directed graphs. We mainly address two aspects of the topological full group. The first is to what ... -
Operator algebras on Wiener amalgam spaces
Svela, Erling Arnold Tønseth (Master thesis, 2022)I denne oppgåva vert operatoralgebraar på Wiener-amalgamrom introdusert og behandla. Først kjem ei grundig innføring til Wiener-amalgamrom på lokalt kompakte grupper, som dreg nytte av både den kontinuerlege og diskrete ... -
Time-Frequency Analysis Meets Quantum Harmonic Analysis
Skrettingland, Eirik (Doctoral theses at NTNU;2021:152, Doctoral thesis, 2021)The subject of this thesis is the study of quantum harmonic analysis and timefrequency analysis, and in particular the intersection of these two fields. Quantum harmonic analysis is studied abstractly both by obtaining new ... -
Twisted Convolution Algebras and Applications to Gabor Analysis
Austad, Are (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 ...
