Zeta finally ended ?

Looks serious.

It seems as though the domain name has expired and has become available again (I think - but my Euro is poor) If so, then I doubt very strongly indeed that it will be back at all, as the project was completed some time ago.

It does appear that Project Zeta has finally tasted dust.

I wonder if JimB0Th can confirm this for us. I have posted in his forum. Perhaps he can obtain some confirmation through his contacts.

In the mean time, as I assume that this is the end of "lots of nothings" :lol: thanks to all of you who gave it a go, threw down gauntlets, picked up places and otherwise gave us challenge.

Vive le Zeta long temps.

Dave,


Dear ZetaGrid Community members.

With achieving our last fourth target (1 trillion verified zeros of the Riemann zeta function) at the end of last year, I just wanted to take a moment to thank you for all you have done to move ZetaGrid forward in the last 3 years.

ZetaGrid started with a small initiative and the first work unit at 3:36pm August 28, 2001 in the Development Lab Boeblingen, Germany. Continuously, this initiative grows up in a worldwide community with the accessibility through the Internet on August 26, 2002. And now this community has about 5,000 members. During this time I have received various significant contributions, e.g. improvements of the software, redesign recommendations, test cases, extensions, documentation, useful hints, and assistance.

Now ZetaGrid can deliver:
1. a robust, scalable and dependable Grid platform for CPU intensive problems 2. a major milestone in the Computational Number Theory
and the Riemann Hypothesis

One major focus was always that the ZetaGrid software package is free. And I know that many of you were unhappy that the downloads of the software package were moved to IBM alphaWorks last year. But this step was important.

At the end of last year, many of you have seen the announcement of reaching a 10 times higher verification (10 trillion zeros) from Gourdon and Demichel than our computational effort. But a world record is always just something for the history. My main objective of this research project was the collection of accurate data about the distribution of the zeros. Now I have reached 20 TB of data and numerous heuristics concerning the Riemann Hypothesis that will be published and hopefully proven soon.

Up to now many of you have asked me about the next step for our community. And I am happy to see this huge interest in complex and fundamental mathematical research in our strong community! This task is definitly completed (but will still run for a while) and I also spent effort to understand the implementation of the faster algorithm of Gourdon and Demichel. But the implementation of this faster computation is not accurate enough for my research concerns. I see the opportunity to extend our computational task to the Extended Riemann Hypothesis. But I suggest to discuss this topic in our community forum.

So, please accept my sincere thanks for everything you have done and my best wishes to you.

Sebastian

Zeta is a dead project since January 2005.

[AMDave]

Thanks Carlos.
We read that in January too.


... as the project was completed some time ago.

I am referring to the fact that the server has finally stopped accepting WUs and the website has gone.

[NeoGen]

Another one to the finished ones.

I guess it will reduce a little on Ototero's stats workload. :)

[Ototero]

No Neo, 2 out, 2 in :D :D :D :D

[AMDave]

Down but not out - Zeta returns

The domain is valid for another year.

-> THANKS JimB0Th

ALSO I had not seen this subsequent post in the Zeta Forum on 22nd January 05 (after that noted by Carlos, above)


Dear ZetaGrid Community member:

Thank you for all your feedback. I noticed that many of you guess that the contribution to the ZetaGrid computation was for nothing since we achieved "just" 1 trillion verified zeros of the Riemann zeta function
and now there is an announcement of reaching a 10 times higher verification.

Most scientists (also me) believe that the Riemann Hypothesis is true. Hence, just verifying trillion of zeros and announcing them was not our main objective. Again, the main objective of this research project was the collection of accurate data about the distribution of the zeros.

In fact, we (maybe) achieved a real mathematical milestone in the 140 year old Riemann Hypothesis that is still the "most important unsolved problem of mathematics."

Our milestone will be:
At least 70% of all nontrivial zeros lie on the critical line.

In other words: With this conjecture (or theorem if the proof is completed), we did not prove the Riemann Hypothesis but we made - what most scientists believe - now measurable, i.e. the Riemann Hypothesis is correct for at least 70% of all cases. And our achievement could not be checked without computers and your help. For the non-mathematician, the Riemann zeta function has infinitely many zeros such that just a computational verification of the zeros does not directly achieve the above milestone. So, this conjecture is correct for infinitely many zeros.

The proof is not completed! Usually as mathematician it is not creditable to announce something without a rigorous proof. But now it is more important for me that this community understood our real achievements.

We are the leading edge research community for the Riemann Hypothesis!
We have achieved very much, we will achieve more, and ZetaGrid continues...

Best wishes,
Sebastian


P.S.
Later, I will precise why I chose IBM alphaWorks as my major sponsor.

Seems she ain't goin' down without a fight :cool:

[NeoGen]

I never believed ressurections... but seems Zetagrid has come back from the dead... :lol:

[Ototero]

I'll put it back in the stats then.
