The Faulhaber Formula Analytic Continuation (2107.04972v3)

Abstract: We extend the Faulhaber formula to the whole complex plane, obtaining an expression that fully resembles the Euler-Maclaurin summation formula, only it's exact. Thereafter, an expression for the generalized harmonic progressions valid in the whole complex plane is also derived. Lastly, we extend a formula for the Hurwitz zeta function valid at the negative integers, $\zeta(-k,b)$, to the whole complex plane, following a similar procedure.
