comment Did Landau prove that there is a prime on $(x,(1+1/5)x)?$
The answer is no. Landau's expression for the difference is the problem.

comment Special case of prime number theorem for arithmetic progressions 4k+1
@user110706: it is no bother but the problem appears somewhat involved and my time's a little short. i can begin to think about it.

comment Proof of Andrica when Assuming Oppermann
@GottfriedHelms: Sorry, I told with OP that I would help him with presentation and then delete the answer as it was not really an answer. Thank you for the explanation which is what I finally decided you meant. I think OP is still thinking about changes in the form of the question but for sure must include your suggested expansion. Yes the truth of the inequality I think does it.

comment Why were proofs avoiding complex analysis preferred in number theory? Is this distinction still important?
It wasn't silly to Erdos or Selberg. Have we evolved that quickly?

comment Source of Hardy-Littlewood's 2nd Conjecture
@GerryMyerson: Your answer makes it clear why this paper is the source of HL2 despite fixed x (in the paper). My answer omits this because I didn't find the cites and was willing to assume that people simply copied some early misapprehension (which probably many have). If you cross-post your better answer here I will happily take mine down.
