But it raises the question of what, in modern parlance, is “canon”.

As far as I can tell, mathematics that becomes canonical if enough mathematicians think it’s beautiful. There is plenty of seriously presented mathematics that never achieves canon status. The practical effect of being canon is that other mathematicians care to do proofs with it, or about it. Riemann’s hypothesis is canon even though it hasn’t been proven, because so many proofs use it as an axiom. ]]>
