Erdos numbers
As a bit of light relief, and to give folk here an opportunity to indulge in some almost meaningless boasting, I'd like people to post their Erdos number. Those who don't know what an Erdos number is should look it up in the standard places.
To get things started: Mine is 2 (via Sam Wagstaff) Ernst Mayer's is 3 (via Richard Crandall and Carl Pomerance) Bob Silverman's is 2 (via John Brillhart). Ernst and I are four apart (Crandall, Pomerance and Wagstaff intervening) whereas Bob and I are linked through Wagstaff. Bob has precisely the same separation from Ernst as I do. If either of the two above disagree with my analysis, please let me know! Paul Last fiddled with by xilman on 20051029 at 22:06 Reason: Can't spell "indulge" without a good long runup at it.

Mine is largest, guess what it is?
edit: This should be moved to the msl thread or lounge as it is not math. Last fiddled with by Citrix on 20051029 at 22:48

my erdos number is infinity, however, there is a guy out there with my same exact name (first, last AND middle) who as far as I've gleaned from google studied at Berkeley and held a postdoctoral position at Harvard in (I think) chemistry .. and it looks like homeboy's been busy (wrt writing papers) so I wouldn't be surprised if HE had an Erdos number.

I'd argue that its mathrelated but you're right: it's better in the Lounge. Paul

I regret that I am what Paul (Erdos, that is) would have referred to as one of the great unwashed who has never published a math paper. My only connection with the man is that I am (like him) a fervent believer in the efficacy of coffee to the thinking process.
My favourite quote from him is: A mathematician is a machine for turning coffee into theorems.

I personally know a man (Roberto Vacca) who has his Erdos number, but I'm afraid I can't qualify for it, as his question related to an Erdos' hypothesis remains unanswered Luigi

For example, as of 2 weeks ago, I have a Lemmy number of 3. Not as good as my Ronnie James Dio number of 2, alas. (Well, we aren't in the maths forum any more!) Phil

more than one path to the root and that the minimum length is k. If one has r such paths, (i.e. r different paths of length k), then the Erdos number is (k1) + 1/r. I have several different paths of length 2. (with Peter Montgomery and Sam as well, and one *unpublished* path with my ex). Under this "convention" my number is 1 1/3. My ex had an Erdos number of 1.

I've a path with Peter Montgomery too, so under that convention my Erdos number is (21)+1/2 = 3/2. I'm fairly sure all my other coauthors have a regular Erdos number of at least two, though would be delighted to learn otherwise. Paul
