That is, the Gamma function is log-convex for positive values of x. I mention this fact because one can prove that given a function Γ(x) that satisfies Γ(1) = 1, xΓ(x) = Γ(x + 1) and is log-convex for 0 < x < ∞, then this function is uniquely defined. Moreove...
The logarithmic derivative of the gamma function (z) can be represented in terms of a generalized hypergeometric function. Using results of our previous studies, we can approximate (z) by a sequence of ratios of polynomials. The sequence converges in the half-plane R(z) > 0. Further, ...

Figure 17(a) illustrates the effect of using the log derivative function to normalize the waveform and to identify the zero crossings of the complex zeros. By rectifying the waveform we get the halfwave pulse events as shown in Figure 17(b), and in 17(c) we see the real and complex ze...
