  • Eigenfunctions of the Cosine and Sine Transforms 
    Katsnelson, V. (Журнал математической физики, анализа, геометрии, 2013)
    A description of the eigensubspaces of the cosine and sine operators is given. The spectrum of each of these two operators consists of two eigen- values 1, -1 and their eigensubspaces are infinite{dimensional. There are ...
  • The Truncated Fourier Operator. General Results 
    Katsnelson, V.; Machluf, R. (Журнал математической физики, анализа, геометрии, 2012)
    Let F be the one dimensional Fourier-Plancherel operator and E be a subset of the real axis. The truncated Fourier operator is the operator FE of the form FE = PEFPE, where (PEx)(t) = 1IE(t)x(t), and 1IE(t) is the indicator ...
