given the function
[tex] arg\xi(1/2+is) [/tex]
is this an increasing function of 's' ?? , i mean if its derivative is always bigger than 0
here xi is the Riemann Xi function
http://en.wikipedia.org/wiki/Riemann_Xi_function
could we define the 'inverse' (at least for positive s) of [tex] arg\xi(1/2+is) [/tex] ?
