   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Jose Eduardo Vasquez; [2021]
   Keywords : Wiener-Lévy Theorem; Wiener s Lemma; Fourier series; Complex analysis;

   Abstract : The purpose of this thesis is to formulate and proof some theorems about convergences of Fourier series. In essence, we shall formulate and proof Wiener's lemma and Wiener-Lévy theorem which give us weaker conditions for absolute convergence of Fourier series. READ MORE

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

   University essay from Linnéuniversitetet/Institutionen för matematik (MA)

   Author : Albin Petersson; [2019]
   Keywords : ;

   Abstract : 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. READ MORE
