“…[32,) to invert numerically a finite product approximation of the righthand side of (1.9) leading to the desired values of P(J 2 x), for specified choices of x. For related methods of the kind, refer to [30,38,39] (see Remark 2.1 in the sequel). This, in turn, requires a prior explicit knowledge of the eigenvalues {λ k : k 1}, which are implicit in terms of…”
