Closed Forms of Certain Zeta constants?



The Riemann Zeta function ζ(s)=n=11ns converges for Re(s)>1. I am interested in some particular "irrational " values of it such as:




  • ζ(π)=1.176241738,

  • ζ(e)=1.2690096043,

  • ζ(2)=3.020737679,





Are there closed form representations for these and constants? Are there formulas which consists of these constants?


Answer



There is no reason to suspect that these have a "closed form". There isn't even a known closed form for ζ(3)...
