About

For questions about approaches and techniques for discovering a proof, as opposed to writing it down clearly (which involves ). Should not be used unless the focus is on the technique of the proof instead of the solution.

Examples include:

  • Can I prove there are infinitely many primes without using contradiction?
  • What techniques can you use to show that two spaces are homeomorphic?

This tag should not be confused with the tag.

See here for a useful set of guidelines for writing a solution.
