Abstract:
In this paper, we state criteria for the completeness of root subspaces of convolution operators on a finite interval with kernels equal to the Fourier transform of the ratio of two entire functions of exponential type from special classes. We describe a class of entire functions with a regular (in a certain sense) distribution of roots.
Keywords:
convolution operator, completeness of root subspaces, Fourier transform, entire function, function of exponential type, basis property of root vectors, Hilbert–Schmidt operator.
