It's a well-known fact that
limn→∞(Hn−log(n))=γ.
If I use that Γ(1n)≈n when n is large, then I wonder if it's possible to compute the following limit in a closed-form
limn→∞(1Γ(11)+1Γ(12)+⋯+1Γ(1n)−log(Γ(1n))),
where I called ∞∑k=11Γ(1k) as Gammaharmonic series.
I can get approximations, but I cannot get the precise limit, and I don't even know if it can be expressed in terms of known constants.
A 500 points bounty moment: I would enjoy pretty much finding a solution (containing a closed-form) for the posed limit, hence the generous bounty. It's unanswered for 3 years and 8 months, and it definitely deserves another chance. Good luck!
