Analogues of P vs. NP in the history of mathematics
This is a great example, especially because Bolyai has actually expected hyperbolic geometry to be consistent, and mapped out some theorems for it, though he couldn't prove that. |

Could you replace the vertical bars with $ \lfloor\dots\rfloor $ floor signs to make the notation more recognizable? |
