Before publishing a paper, is there any resource to get someone to review/ provide feedback for a mathematical aficionado ?
I am specifying the aficionado because I lack any friend/professor able to check the paper. This is the reason why other pointed questions do not fully address the particularities of this.
Furthermore to add extra constrains the article addresses a famous open problem in number theory, so I am afraid any style error may make the review process unsuccessful as people will immediately think: another no-one believing has solved Riemann's Hypothesis.
Those two reasons: the particular topic of the publication, and my total lack of background in the math publications makes this question different from the pointed one.
