• TITLE: Numerical Approximation of Real Finite Nonnegative Function by the Modulus of Discrete Fourier Transform

  AUTHORS: Petro Savenko, Myroslava Tkach

  KEYWORDS: Mean-Square Approximation, Discrete Fourier Transform, Two-Dimensional Nonlinear Integral Equation, Nonuniqueness And Branching of Solutions

  JOURNAL NAME: Applied Mathematics, Vol.1 No.1, June 2, 2010

  ABSTRACT: The numerical algorithms for finding the lines of branching and branching-off solutions of nonlinear problem on mean-square approximation of a real finite nonnegative function with respect to two variables by the modulus of double discrete Fourier transform dependent on two parameters, are constructed and justified.
