Estimating the zeroes and the optimal Growth of a functional :

75 Views Asked by At

Consider the following functions :

$$F(z,s)=\frac{\sin^2(\frac{c\Gamma(z)}{z})}{z^s}$$

Here, $c$ is a real constant and $s\in[0,1]$ .

Now we have to find the nature of following functional(w.r.t. given domain of $s$) :

$$\int_0^\infty\frac{F(x + iy,s) − F(x − iy,s)}{e^{2πy}-1} dy $$

as $x→∞$

Also how to analyse (for) it's zeros and local extremas (efficiently) ?
