suppose that in the sense of distribution $ \int_{0}^{\infty}dxx^{n}T(x,s) =n^{s} $
for some distribution $ T(x) $ i do not know :(
so if we apply borel generalized resummation
$$ 1+2^{s}+3^{s}+......= \int_{0}^{\infty}( \sum_{n=1}^{\infty}\frac{x^{n}}{n^{s}})T(x,s) $$
the first term inside the integral is just $ Li_{s}(x) $
but now i am stuck because i do not know how $ T(x,s) $ should be to get a coherent result for borel resummation
