 open problems survey bo198214 Administrator Posts: 1,389 Threads: 90 Joined: Aug 2007 07/20/2010, 05:50 AM (This post was last modified: 10/24/2010, 07:55 AM by bo198214.) Let the sequence $(a_n)_{n\in\mathbb{N}}$ be defined recursively in the following way for $b>0$: $a_1 = 1$ and $a_n = \frac{1}{1-b^n}\sum_{m=1}^{n-1} a_m \left(n\\m\right) (1-b)^{n-m} b^m$ for $n\ge 2$ Is $\lim_{n\to\infty} a_n = \frac{b-1}{\ln(b)}$? The conjecture is proven to be true. See http://arxiv.org/abs/1008.1409 and also the discussions: Logarithm reciprocal True or false logarithm There is also a result-less (as of this writing) thread in sci.math.research and sci.math called "Logarithm reciprocal". « Next Oldest | Next Newest »
