    • Boundary Properties of Modified Zeta Functions and Function Spaces of Dirichlet Series 

      Olsen, Jan-Fredrik (Doktoravhandlinger ved NTNU, 1503-8181; 2009.91, Doctoral thesis, 2009)
      Ordinary Dirichlet series, of which the Riemann zeta function is the most important, play a prominent role in classical analysis and number theory, and in modern mathematics. It is well-known that the Riemann zeta function ...

    • Existence of uncertainty minimizers for the continuous wavelet transform 

      Halvdansson, Karl Simon; Olsen, Jan-Fredrik; Levie, Ron; Sochen, Nir (Peer reviewed; Journal article, 2023)
      Continuous wavelet design is the endeavor to construct mother wavelets with desirable properties for the continuous wavelet transform (CWT). One class of methods for choosing a mother wavelet involves minimizing a functional, ...
