Mar 5, 2023 at 3:21 comment added Martin Sleziak The "citeseer" link no longer works - but after changing URL to citeseerx one can see that it was a link to the paper Pascal Koiran: Hilbert's Nullstellensatz is in the Polynomial Hierarchy.
Nov 20, 2013 at 12:38 comment added Lior Silberman Similarly, polynomials over finite fields can be deterministically factored in polynomial time under GRH; unconditionally only a randomized algorithm is known.
Nov 14, 2013 at 13:42 comment added Emil Jeřábek While primality testing is in P, there are other examples of similar sort that are unsettled. Square roots modulo primes can be computed in randomized polynomial time by the Tonelli–Shanks algorithm which can be derandomized assuming the GRH, but no unconditional deterministic polynomial-time solution is known. See also arxiv.org/abs/1207.5220 (if I may).
Nov 13, 2013 at 13:43 comment added usul A straightforward connection is that, if GRH holds, then the Miller-Rabin primality test is correct in deterministic polynomial time. This would have proven the open question "PRIMES in P" ... until the AKS test was discovered and settled the question independently of GRH!

arthur-merlin inside second level; necessity of GRH unknown to me.
Nov 12, 2013 at 2:12 comment added Noah Schweber Is it known whether GRH is necessary for of Koiran's result?
