I know values of zeta for s= 2,3,4,... but what's the value of zeta as an example s= 2+14i
Does Zeta converge for Complex numbers Re(s)>1 where imaginary part is not zero?

0Yes the series $\sum_{n=1}^\infty n^{-s}$ converges whenever $\mathrm{Re}(s)>1$, regardless of the imaginary part of $s$. A standard comparison test should suffice. Also, the body of your question seems to be asking for explicit values of the zeta function at nonreal arguments. Do you want numerical values (which e.g. WolframAlpha can spit out easily), or closed-form symbolic expressions? (If the latter, I have a hard time believing you know the value of $\zeta$ for $s=3$.) – 2012-10-17

0Probably Mr Chuy should spend some more time working on analysis ... it will surely help him if he wants to work on the zeta function. – 2012-11-08
