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!
