Is there overmuch reason to believe this latest announced proof, given the amazing record of the Jacobian problem for eliciting bogus proofs from mathematicians of considerable ability and reputation (as well as others, naturally)? Has, for instance, anyone else with relevant expertise endorsed it yet?
