Any obligation, no.<p>But the consensus among the mathematical community is that Mochizuki probably doesn&#x27;t have a proof, that his work likely has some fundamental error, that it is probably (but not certainly) not worth taking all that seriously.<p>If Mochizuki doesn&#x27;t mind this, then that&#x27;s fine. But if he wants the respect that he claims to deserve, then the &#x27;roadshow&#x27; can&#x27;t be omitted.
