Guido Mislin retired from ETHZ on June 26th, 2006

and a bunch of his fans got together to make him a retirement gift.

June 26th, 2006: Guido gave a really cool Abschiedsvorlesung on Bernoulli numbers, and received the book of conjectures at the end, click here to see pictures (courtesy of Michele Marcionelli).
OF COURSE: I am not taking any more contributions or corrections... so please if you see typos don't tell me!
See the final product: Click here.
To all contributors: THANK YOU so much for making that possible, have a nice Summer and keep checking that web page for a possible "season 2" of the project!

Below are the archives, if you want to see how the project built on.

GUIDELINES:

Dear Friends of Guido,
Guido Mislin is retiring on the 26th of June and we would like to make him a small retirement gift. It should be a surprise so please be quiet. Since Guido likes conjectures, we want to offer him a book on it: If you write MAX 2 PAGES (but it could be much less provided Guido will enjoy reading it) on a conjecture or an open question you would like to share with him, we'll have a fantastic present. Don't write much, keep it low key and informal. To avoid doubles, who does what and headers will be available below, please bookmark that page since there is no external link to it, and keep checking it for updates on the project.
Collaborations are encouraged and there is no upper bound on the size of a team, but the text should not exceed 2 pages per topic regardless. Contributions will ultimately be in alphabetical order. Please write it up in a very low key LaTeX style, with the headers at the end of the message, following the commented instructions and send your contribution to indira@math.ohio-state.edu
Thank you!
Indira Chatterji, Mike Davis, Henry Glover and Tadeusz Januszkiewicz.

TIME LINE:
  • Everyone should know his title (and team if in a team) by the 22nd of May but the sooner the better, you should decide right now what you write, contact the natural person to write with if any and e-mail me an explicit title so that I can post on-line who does what.
  • There will be one draft only, that draft has to be sent to me by June 5th (but the sooner the better).
  • June 12th all the authors will receive the whole file for galley proof-reading and typo hunting.
  • Changed I want to be able to print out the final pdf-file the 16th of June to have time to make a nice binding to give him on the 26th at his retirement lecture. I know that this is very short notice and I whish I had been better organized, but that should take only a moment of very rewarding thoughts on your favorite field of expertise (so I don't feel that bad asking you that).
