# New proofs of some formulas of Guillera-Ser-Sondow

@article{Bolbachan2009NewPO, title={New proofs of some formulas of Guillera-Ser-Sondow}, author={Vassily Bolbachan}, journal={arXiv: Number Theory}, year={2009} }

We present logarithmic series for u, ln u and the Euler-Mascheroni constant gamma. It was indicated by J. Sondow that Theorem 4 and all proofs are new. All proofs are elementary. We present some conjectures.

### Three Notes on Ser's and Hasse's Representations for the Zeta-functions

- MathematicsIntegers
- 2018

This paper shows that the famous Hasse's series for the zeta-function is equivalent to an earlier expression given by a little-known French mathematician Joseph Ser in 1926, and shows that there exist numerous series of the same nature.

### Rational approximants for the Euler-Gompertz constant

- Mathematics
- 2011

We obtain two sequences of rational numbers which converge to the Euler-Gompertz constant. Denote by the integral of f(x)e^{-x} from 0 to infinity. Recall that the Euler-Gompertz constant \delta is .…
