Erdős, Paul Some solved and unsolved problems of mine in number theory. (English) Zbl 0596.10001 Topics in analytic number theory, Proc. Conf., Austin/Tex. 1982, 59-75 (1985). [For the entire collection see Zbl 0589.00007.] This article contains many old and new problems on primes, divisors, etc., with comments and partial results. A number have prizes attached. The one with the smallest non-zero-prize (and so the easiest?) asks that if \(d_n\) is the difference \(p_{n+1}-p_n\) between consecutive primes, then \(d_{n+1}-d_n\) and \(d_{n+1}-d_{n+2}\) should have opposite signs infinitely often.
