Welcome to the Open Problem Garden, a collection of unsolved problems in mathematics. Here you may:
- Read descriptions of open problems.
- Post comments on them.
- Create and edit open problems pages (please contact us and we will set you up an account. Unfortunately, the automatic process is too prone to spammers at this moment.)
Help us Grow!
We are eager to expand, so we are inviting contributions both large and small from all areas of mathematics.
Many thanks to our contributors!
About
Created by Matt DeVos and Robert Šámal during the 2006-07 academic year.
Thanks to the many people who helped us put this site together:
- Bojan Mohar for support and for contributing the problems from his wonderful Problem of the month.
- Wendell Challenger and his website fearlessgearless for convincing us to use Drupal
- The Drupal community for helping us to build what we imagined.
- IRMACS and especially Dominic Lepiane for technical support while creating the site and in the first years of its existence.
- Luis Goddyn, Jacob Groundwater, Veselin Jungic, and Bojan Mohar for numerous helpful discussions.
- Computer Science Institute of Charles University for hosting our site

Step by step instructions
| Field | Guidelines | ||||||||
| Title | The title used by the Garden for reference purposes. | ||||||||
| Statement | A concise statement of the conjecture. Please keep this short, even at the cost of postponing essential definitions to the body. | ||||||||
| Importance |
|
||||||||
| Authors | The authors of the conjecture in a list separated by semicolons. Please use the format Lastname, Firstname I., and please pause to let autocomplete "guess" author names to prevent multiple copies of the same author. | ||||||||
| Area » Topic » Subtopic | The subject the open problem belongs in. Every problem must be assigned an Area, but problems need not be assigned a Topic or Subtopic. Please assign your problem the most reasonable classification possible, and contact us ("Contact" button in upper right hand corner) if the appropriate subject does not exist. | ||||||||
| Keywords | key words used for reference purposes. Separate by semicolons. | ||||||||
| Recommended for undergrads | "yes" if the problem looks suitable for an undergraduate and "no" otherwise. | ||||||||
| Prize | If there is a prize for this conjecture, a description of it, and who offered it. | ||||||||
| Status | "open" if the problem is unsolved, and "solved" otherwise. If the problem is solved, indicate the solver and reference for the paper in the extra field. | ||||||||
| Discussion | A discussion of the problem. This is a LaTeX field where you can use all of the commands in the table below. We encourage you to use Wikipedia for definitions of standard terms. If Wikipedia is lacking here, update it! | ||||||||
| Related Problems | A list of related problems. | ||||||||
| Bibliography | A bibliography for the problem. We indicate original appearances of the problem with an *, and provide links to the paper and to MathSciNet when possible. |

backup
In ~/bin/back_it_up is a script that back the whole database (and creates a separate directory for it: ~/Bak/2007_02_27-...).
Later we should find out how to do this automatically and regularly.
biblio module
Very nice feature: "citekey": see http://drupal.org/node/89038
(Seemingly this does not work in our version of the module.)
