As the Riemann hypothesis is the central problem in mathematics but it is yet unsolved. On the other hand when you search for proof of RH. There are lot of PDFs containing various proof and disproof but RH is still unsolved. Why?
@JoséCarlosSantos Consider what would happen if someone came into this room to see that you have called their post "useless". Do you think that this is an approach that is likely to be welcoming to those people? Do you think that people whose work is discussed in this way are likely to want to hear further advice about how they can improve?
In general, please try to keep the language in this room neutral. Imagine that the authors of the posts being discussed here are in the room.
