Can Mathematica verify the Cahen-Mellin integral?
When I try
Integrate[Gamma[1 + I s]/Zeta[3]^(1 + I s), {s, -Infinity, Infinity}]
I just get the input back. Thanks for any suggestion!
EDIT:
Numerically it is easy to get agreement:
NIntegrate[Gamma[1 + I s]/Zeta[3]^(1 + I s), {s, -Infinity, Infinity}]
1.88857 + 2.26472*10^-13 I
2 \[Pi] Exp[-Zeta[3]] // N
1.88857
But I wonder whether Mathematica more generally is capable of doing such integrals analytically.
Integrate
rather thanInverseMellinTransform
? If so, slightly related: mathematica.stackexchange.com/q/81154/1871 $\endgroup$Integrate[Exp[I t q],{t,-Infinity,Infinity}]
either, butFourierTransform[1,t,q]
works perfectly fine. $\endgroup$
