"The discrete Fourier calculus of the four families of special functions, called C-, S-, S-s - and S-l- functions, is summarized. Functions from each of the four families of special functions are discretely orthogonal over a certain finite set of points. The generalizations of discrete cosine and sine transforms of one variable - the discrete S-s - and S-l - transforms of the group F-4 - are considered in detail required for their exploitation in discrete Fourier spectral methods. The continuous interpolations, induced by the discrete expansions, are presented."@en . "1"^^ . "Discretization of four types of Weyl group orbit functions" . . . "10.1088/1742-6596/474/1/012021" .
