1. 1. Characterizations of Gelfand-Shilov Spaces

   Master-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

   Författare :Albin Petersson; [2021]
   Nyckelord :Gelfand-Shilov spaces; Pilipović spaces; STFT; Functional Analysis;

   Sammanfattning : In this thesis we examine properties of Gelfand-Shilov spaces Ssσ and Pilipović spaces Σsσ. These are spaces of smooth functions which, along with their Fourier transforms, decay sub-exponentially. LÄS MER

3. 2. On the Properties of Wiener-Lévy Functions

   Kandidat-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

   Författare :Albin Petersson; [2019]
   Nyckelord :;

   Sammanfattning : This thesis concerns the Wiener algebra of periodic functions with absolutely convergent Fourier series, and the "Wiener-Lévy functions", meaning functions that preserve absolute convergence of Fourier series under composition. Results regarding the properties of functions in the Wiener algebra are established, as well as properties of Wiener-Lévy functions. LÄS MER

4. 3. Förutsättningar för geoenergi till idrottsanläggningar i Kallerstad, Linköpings kommun : en förstudie

   Kandidat-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Albin Petersson; [2012]
   Nyckelord :energibrunn; akvifär; ATES; Geoenergi; BTES; Geothermal energy; aquifer; energy well; Earth and Environmental Sciences;

   Sammanfattning : Because of the sun and geothermal heat the ground has two natural recourses for heat energy, and since the ground changes temperature slower than the air it has a more even temperature fluctuation. This is positive for the use of geothermal energy which is a renewable method that has been given more attention lately due to it positive environmental effects. LÄS MER
