List of conjectures

This is an incomplete list of mathematical conjectures. They are divided into four sections, according to their current status.

See also:

• Erdős conjecture, which lists conjectures of Paul Erdős and his collaborators
• Unsolved problems in mathematics
• List of unsolved problems
• Millennium Prize Problems

and, for proved results,

• List of theorems, list of lemmas;

also

• List of statements undecidable in ZFC

for problems not subject to conventional proof nor disproof.
